Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607256, here are decompositions:

19 + 31607237 = 31607256
29 + 31607227 = 31607256
103 + 31607153 = 31607256
277 + 31606979 = 31607256
283 + 31606973 = 31607256
293 + 31606963 = 31607256
313 + 31606943 = 31607256
337 + 31606919 = 31607256

Showing the first eight; more decompositions exist.
