Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618176, here are decompositions:

13 + 31618163 = 31618176
43 + 31618133 = 31618176
113 + 31618063 = 31618176
127 + 31618049 = 31618176
173 + 31618003 = 31618176
179 + 31617997 = 31618176
223 + 31617953 = 31618176
277 + 31617899 = 31618176

Showing the first eight; more decompositions exist.
