Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594658, here are decompositions:

31 + 31594627 = 31594658
61 + 31594597 = 31594658
79 + 31594579 = 31594658
157 + 31594501 = 31594658
229 + 31594429 = 31594658
307 + 31594351 = 31594658
349 + 31594309 = 31594658
421 + 31594237 = 31594658

Showing the first eight; more decompositions exist.
