Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607934, here are decompositions:

13 + 31607921 = 31607934
31 + 31607903 = 31607934
37 + 31607897 = 31607934
67 + 31607867 = 31607934
103 + 31607831 = 31607934
151 + 31607783 = 31607934
251 + 31607683 = 31607934
263 + 31607671 = 31607934

Showing the first eight; more decompositions exist.
