Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508956, here are decompositions:

113 + 31508843 = 31508956
317 + 31508639 = 31508956
389 + 31508567 = 31508956
449 + 31508507 = 31508956
503 + 31508453 = 31508956
593 + 31508363 = 31508956
797 + 31508159 = 31508956
863 + 31508093 = 31508956

Showing the first eight; more decompositions exist.
