Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606712, here are decompositions:

31 + 31606681 = 31606712
61 + 31606651 = 31606712
283 + 31606429 = 31606712
331 + 31606381 = 31606712
373 + 31606339 = 31606712
433 + 31606279 = 31606712
661 + 31606051 = 31606712
1093 + 31605619 = 31606712

Showing the first eight; more decompositions exist.
