Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596256, here are decompositions:

47 + 31596209 = 31596256
113 + 31596143 = 31596256
137 + 31596119 = 31596256
227 + 31596029 = 31596256
383 + 31595873 = 31596256
389 + 31595867 = 31596256
449 + 31595807 = 31596256
479 + 31595777 = 31596256

Showing the first eight; more decompositions exist.
