Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499118, here are decompositions:

11 + 31499107 = 31499118
41 + 31499077 = 31499118
61 + 31499057 = 31499118
97 + 31499021 = 31499118
127 + 31498991 = 31499118
151 + 31498967 = 31499118
239 + 31498879 = 31499118
251 + 31498867 = 31499118

Showing the first eight; more decompositions exist.
