Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508314, here are decompositions:

3 + 31508311 = 31508314
83 + 31508231 = 31508314
137 + 31508177 = 31508314
311 + 31508003 = 31508314
401 + 31507913 = 31508314
491 + 31507823 = 31508314
521 + 31507793 = 31508314
647 + 31507667 = 31508314

Showing the first eight; more decompositions exist.
