Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509064, here are decompositions:

3 + 31509061 = 31509064
11 + 31509053 = 31509064
47 + 31509017 = 31509064
317 + 31508747 = 31509064
383 + 31508681 = 31509064
443 + 31508621 = 31509064
557 + 31508507 = 31509064
647 + 31508417 = 31509064

Showing the first eight; more decompositions exist.
