It does not tell us anything about the validity of Goldbach's conjecture, because it does:
Any 2 even primes or 2 odd primes > sum is an even number
While his conjecture is
Any even number >= 4 = sum of 2 primes
A implies B
is not equivalent to
B implies A
If a positive integer is a prime other than 2, then it is odd
is not equivalent to
If a positive integer is odd, then it is a prime other than 2
If/then  implication
false > false  true
false > true  true
true > false  false
true > true  true
False can imply true, but true cannot imply false.
