Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594668, here are decompositions:

41 + 31594627 = 31594668
59 + 31594609 = 31594668
71 + 31594597 = 31594668
89 + 31594579 = 31594668
167 + 31594501 = 31594668
179 + 31594489 = 31594668
239 + 31594429 = 31594668
269 + 31594399 = 31594668

Showing the first eight; more decompositions exist.
