It was really close, perhaps the ways you can wright n on is >= the n-1:th prime. But how could i ever prove it?

Finding prime numbers is important in many areas of mathematics, computer science, and cryptography. Prime numbers are the building blocks of all other numbers, and they have unique properties that make them useful in a variety of applications. For example, they are used in encryption algorithms to ensure secure communication.
One way to determine if a number is prime is to use a process called trial division, where you divide the number by every integer from 2 to its square root. If there is no remainder for any of these divisions, the number is prime. Another method is the Sieve of Eratosthenes, which involves creating a list of all numbers up to a certain limit and crossing out multiples of known primes until only the primes remain.
While there are some patterns and rules that can help identify potential prime numbers, there is no definitive formula for finding primes. Prime numbers tend to become more sparse as they get larger, making them more difficult to find. However, there are many ongoing research efforts to find new ways to efficiently find large prime numbers.
While prime numbers may not seem directly relevant to everyday life, they play a critical role in many modern technologies. For example, they are used in computer algorithms for data encryption, which is used in online banking and other secure communications. Prime numbers are also used in computer graphics and data compression.
One reason for finding large prime numbers is to ensure the security of encryption algorithms. As computers become more powerful, larger prime numbers are needed to create stronger encryption. Additionally, finding large prime numbers can also lead to new discoveries in mathematics and help us better understand the properties of these important numbers.
