Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514090, here are decompositions:

31 + 31514059 = 31514090
67 + 31514023 = 31514090
103 + 31513987 = 31514090
163 + 31513927 = 31514090
199 + 31513891 = 31514090
211 + 31513879 = 31514090
241 + 31513849 = 31514090
271 + 31513819 = 31514090

Showing the first eight; more decompositions exist.
