Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614732, here are decompositions:

29 + 31614703 = 31614732
31 + 31614701 = 31614732
89 + 31614643 = 31614732
101 + 31614631 = 31614732
131 + 31614601 = 31614732
173 + 31614559 = 31614732
181 + 31614551 = 31614732
239 + 31614493 = 31614732

Showing the first eight; more decompositions exist.
