Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549314, here are decompositions:

37 + 31549277 = 31549314
73 + 31549241 = 31549314
107 + 31549207 = 31549314
113 + 31549201 = 31549314
131 + 31549183 = 31549314
197 + 31549117 = 31549314
227 + 31549087 = 31549314
233 + 31549081 = 31549314

Showing the first eight; more decompositions exist.
