Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514088, here are decompositions:

7 + 31514081 = 31514088
29 + 31514059 = 31514088
101 + 31513987 = 31514088
131 + 31513957 = 31514088
197 + 31513891 = 31514088
211 + 31513877 = 31514088
239 + 31513849 = 31514088
257 + 31513831 = 31514088

Showing the first eight; more decompositions exist.
