Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549364, here are decompositions:

37 + 31549327 = 31549364
127 + 31549237 = 31549364
157 + 31549207 = 31549364
163 + 31549201 = 31549364
181 + 31549183 = 31549364
277 + 31549087 = 31549364
283 + 31549081 = 31549364
313 + 31549051 = 31549364

Showing the first eight; more decompositions exist.
