Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613118, here are decompositions:

11 + 31613107 = 31613118
127 + 31612991 = 31613118
137 + 31612981 = 31613118
149 + 31612969 = 31613118
157 + 31612961 = 31613118
167 + 31612951 = 31613118
179 + 31612939 = 31613118
227 + 31612891 = 31613118

Showing the first eight; more decompositions exist.
