Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450296, here are decompositions:

5 + 31450291 = 31450296
79 + 31450217 = 31450296
89 + 31450207 = 31450296
179 + 31450117 = 31450296
193 + 31450103 = 31450296
197 + 31450099 = 31450296
239 + 31450057 = 31450296
263 + 31450033 = 31450296

Showing the first eight; more decompositions exist.
