Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594520, here are decompositions:

19 + 31594501 = 31594520
31 + 31594489 = 31594520
127 + 31594393 = 31594520
211 + 31594309 = 31594520
283 + 31594237 = 31594520
439 + 31594081 = 31594520
457 + 31594063 = 31594520
577 + 31593943 = 31594520

Showing the first eight; more decompositions exist.
