Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612650, here are decompositions:

23 + 31612627 = 31612650
29 + 31612621 = 31612650
31 + 31612619 = 31612650
53 + 31612597 = 31612650
61 + 31612589 = 31612650
67 + 31612583 = 31612650
103 + 31612547 = 31612650
137 + 31612513 = 31612650

Showing the first eight; more decompositions exist.
