Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607224, here are decompositions:

17 + 31607207 = 31607224
23 + 31607201 = 31607224
71 + 31607153 = 31607224
137 + 31607087 = 31607224
227 + 31606997 = 31607224
251 + 31606973 = 31607224
281 + 31606943 = 31607224
293 + 31606931 = 31607224

Showing the first eight; more decompositions exist.
