Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594660, here are decompositions:

47 + 31594613 = 31594660
107 + 31594553 = 31594660
113 + 31594547 = 31594660
197 + 31594463 = 31594660
239 + 31594421 = 31594660
389 + 31594271 = 31594660
467 + 31594193 = 31594660
509 + 31594151 = 31594660

Showing the first eight; more decompositions exist.
