Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549296, here are decompositions:

19 + 31549277 = 31549296
59 + 31549237 = 31549296
89 + 31549207 = 31549296
113 + 31549183 = 31549296
179 + 31549117 = 31549296
197 + 31549099 = 31549296
257 + 31549039 = 31549296
277 + 31549019 = 31549296

Showing the first eight; more decompositions exist.
