Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612736, here are decompositions:

3 + 31612733 = 31612736
7 + 31612729 = 31612736
73 + 31612663 = 31612736
109 + 31612627 = 31612736
139 + 31612597 = 31612736
163 + 31612573 = 31612736
223 + 31612513 = 31612736
283 + 31612453 = 31612736

Showing the first eight; more decompositions exist.
