Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567944, here are decompositions:

13 + 31567931 = 31567944
61 + 31567883 = 31567944
131 + 31567813 = 31567944
227 + 31567717 = 31567944
251 + 31567693 = 31567944
257 + 31567687 = 31567944
263 + 31567681 = 31567944
271 + 31567673 = 31567944

Showing the first eight; more decompositions exist.
