Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549302, here are decompositions:

61 + 31549241 = 31549302
101 + 31549201 = 31549302
251 + 31549051 = 31549302
263 + 31549039 = 31549302
283 + 31549019 = 31549302
293 + 31549009 = 31549302
349 + 31548953 = 31549302
431 + 31548871 = 31549302

Showing the first eight; more decompositions exist.
