Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508684, here are decompositions:

3 + 31508681 = 31508684
7 + 31508677 = 31508684
13 + 31508671 = 31508684
37 + 31508647 = 31508684
127 + 31508557 = 31508684
157 + 31508527 = 31508684
223 + 31508461 = 31508684
241 + 31508443 = 31508684

Showing the first eight; more decompositions exist.
