Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607706, here are decompositions:

17 + 31607689 = 31607706
19 + 31607687 = 31607706
23 + 31607683 = 31607706
107 + 31607599 = 31607706
127 + 31607579 = 31607706
233 + 31607473 = 31607706
257 + 31607449 = 31607706
283 + 31607423 = 31607706

Showing the first eight; more decompositions exist.
