Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508116, here are decompositions:

23 + 31508093 = 31508116
89 + 31508027 = 31508116
113 + 31508003 = 31508116
239 + 31507877 = 31508116
293 + 31507823 = 31508116
449 + 31507667 = 31508116
509 + 31507607 = 31508116
593 + 31507523 = 31508116

Showing the first eight; more decompositions exist.
