Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541302, here are decompositions:

5 + 31541297 = 31541302
59 + 31541243 = 31541302
173 + 31541129 = 31541302
251 + 31541051 = 31541302
263 + 31541039 = 31541302
281 + 31541021 = 31541302
311 + 31540991 = 31541302
431 + 31540871 = 31541302

Showing the first eight; more decompositions exist.
