Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594628, here are decompositions:

19 + 31594609 = 31594628
31 + 31594597 = 31594628
127 + 31594501 = 31594628
139 + 31594489 = 31594628
199 + 31594429 = 31594628
229 + 31594399 = 31594628
277 + 31594351 = 31594628
547 + 31594081 = 31594628

Showing the first eight; more decompositions exist.
