Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607944, here are decompositions:

23 + 31607921 = 31607944
41 + 31607903 = 31607944
47 + 31607897 = 31607944
113 + 31607831 = 31607944
197 + 31607747 = 31607944
227 + 31607717 = 31607944
257 + 31607687 = 31607944
521 + 31607423 = 31607944

Showing the first eight; more decompositions exist.
