Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508594, here are decompositions:

37 + 31508557 = 31508594
67 + 31508527 = 31508594
151 + 31508443 = 31508594
283 + 31508311 = 31508594
307 + 31508287 = 31508594
367 + 31508227 = 31508594
487 + 31508107 = 31508594
577 + 31508017 = 31508594

Showing the first eight; more decompositions exist.
