Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612732, here are decompositions:

3 + 31612729 = 31612732
5 + 31612727 = 31612732
71 + 31612661 = 31612732
113 + 31612619 = 31612732
149 + 31612583 = 31612732
251 + 31612481 = 31612732
419 + 31612313 = 31612732
491 + 31612241 = 31612732

Showing the first eight; more decompositions exist.
