Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509076, here are decompositions:

23 + 31509053 = 31509076
47 + 31509029 = 31509076
59 + 31509017 = 31509076
233 + 31508843 = 31509076
419 + 31508657 = 31509076
509 + 31508567 = 31509076
569 + 31508507 = 31509076
659 + 31508417 = 31509076

Showing the first eight; more decompositions exist.
