Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596514, here are decompositions:

3 + 31596511 = 31596514
17 + 31596497 = 31596514
41 + 31596473 = 31596514
101 + 31596413 = 31596514
113 + 31596401 = 31596514
197 + 31596317 = 31596514
641 + 31595873 = 31596514
647 + 31595867 = 31596514

Showing the first eight; more decompositions exist.
