Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607732, here are decompositions:

43 + 31607689 = 31607732
61 + 31607671 = 31607732
103 + 31607629 = 31607732
151 + 31607581 = 31607732
181 + 31607551 = 31607732
229 + 31607503 = 31607732
271 + 31607461 = 31607732
283 + 31607449 = 31607732

Showing the first eight; more decompositions exist.
