Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618314, here are decompositions:

17 + 31618297 = 31618314
83 + 31618231 = 31618314
103 + 31618211 = 31618314
127 + 31618187 = 31618314
151 + 31618163 = 31618314
181 + 31618133 = 31618314
193 + 31618121 = 31618314
251 + 31618063 = 31618314

Showing the first eight; more decompositions exist.
