Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508674, here are decompositions:

3 + 31508671 = 31508674
17 + 31508657 = 31508674
23 + 31508651 = 31508674
53 + 31508621 = 31508674
107 + 31508567 = 31508674
167 + 31508507 = 31508674
257 + 31508417 = 31508674
311 + 31508363 = 31508674

Showing the first eight; more decompositions exist.
