Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508714, here are decompositions:

31 + 31508683 = 31508714
37 + 31508677 = 31508714
43 + 31508671 = 31508714
67 + 31508647 = 31508714
157 + 31508557 = 31508714
271 + 31508443 = 31508714
487 + 31508227 = 31508714
571 + 31508143 = 31508714

Showing the first eight; more decompositions exist.
