Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508134, here are decompositions:

41 + 31508093 = 31508134
107 + 31508027 = 31508134
131 + 31508003 = 31508134
233 + 31507901 = 31508134
257 + 31507877 = 31508134
311 + 31507823 = 31508134
347 + 31507787 = 31508134
431 + 31507703 = 31508134

Showing the first eight; more decompositions exist.
