Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508110, here are decompositions:

3 + 31508107 = 31508110
17 + 31508093 = 31508110
71 + 31508039 = 31508110
83 + 31508027 = 31508110
107 + 31508003 = 31508110
197 + 31507913 = 31508110
233 + 31507877 = 31508110
317 + 31507793 = 31508110

Showing the first eight; more decompositions exist.
