Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514082, here are decompositions:

23 + 31514059 = 31514082
59 + 31514023 = 31514082
139 + 31513943 = 31514082
191 + 31513891 = 31514082
233 + 31513849 = 31514082
239 + 31513843 = 31514082
251 + 31513831 = 31514082
263 + 31513819 = 31514082

Showing the first eight; more decompositions exist.
