Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615314, here are decompositions:

41 + 31615273 = 31615314
97 + 31615217 = 31615314
103 + 31615211 = 31615314
127 + 31615187 = 31615314
151 + 31615163 = 31615314
251 + 31615063 = 31615314
307 + 31615007 = 31615314
373 + 31614941 = 31615314

Showing the first eight; more decompositions exist.
