Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582304, here are decompositions:

37 + 31582267 = 31582304
97 + 31582207 = 31582304
211 + 31582093 = 31582304
277 + 31582027 = 31582304
283 + 31582021 = 31582304
307 + 31581997 = 31582304
331 + 31581973 = 31582304
421 + 31581883 = 31582304

Showing the first eight; more decompositions exist.
