Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607712, here are decompositions:

23 + 31607689 = 31607712
29 + 31607683 = 31607712
41 + 31607671 = 31607712
83 + 31607629 = 31607712
113 + 31607599 = 31607712
131 + 31607581 = 31607712
181 + 31607531 = 31607712
223 + 31607489 = 31607712

Showing the first eight; more decompositions exist.
