Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508996, here are decompositions:

37 + 31508959 = 31508996
109 + 31508887 = 31508996
139 + 31508857 = 31508996
283 + 31508713 = 31508996
313 + 31508683 = 31508996
349 + 31508647 = 31508996
439 + 31508557 = 31508996
487 + 31508509 = 31508996

Showing the first eight; more decompositions exist.
