Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514046, here are decompositions:

23 + 31514023 = 31514046
59 + 31513987 = 31514046
79 + 31513967 = 31514046
89 + 31513957 = 31514046
103 + 31513943 = 31514046
167 + 31513879 = 31514046
173 + 31513873 = 31514046
197 + 31513849 = 31514046

Showing the first eight; more decompositions exist.
