Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607296, here are decompositions:

3 + 31607293 = 31607296
5 + 31607291 = 31607296
59 + 31607237 = 31607296
89 + 31607207 = 31607296
257 + 31607039 = 31607296
317 + 31606979 = 31607296
353 + 31606943 = 31607296
449 + 31606847 = 31607296

Showing the first eight; more decompositions exist.
