Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607656, here are decompositions:

167 + 31607489 = 31607656
233 + 31607423 = 31607656
257 + 31607399 = 31607656
293 + 31607363 = 31607656
347 + 31607309 = 31607656
359 + 31607297 = 31607656
419 + 31607237 = 31607656
449 + 31607207 = 31607656

Showing the first eight; more decompositions exist.
