Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565314, here are decompositions:

5 + 31565309 = 31565314
17 + 31565297 = 31565314
23 + 31565291 = 31565314
83 + 31565231 = 31565314
107 + 31565207 = 31565314
197 + 31565117 = 31565314
227 + 31565087 = 31565314
257 + 31565057 = 31565314

Showing the first eight; more decompositions exist.
