   How do I find out if 4^2007 + 2007^4 is a prime number or not?

   Is that a question or a puzzle?

   Write a program and let the computer figure it out.

   I will tell you, it's not prime; I don't want to say more.

   try using modular arithmetic. i.e. p divides N if N is congruent to 0 modp.
   
   this is not speculation, this is a hint.
