Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612586, here are decompositions:

3 + 31612583 = 31612586
13 + 31612573 = 31612586
73 + 31612513 = 31612586
157 + 31612429 = 31612586
163 + 31612423 = 31612586
223 + 31612363 = 31612586
277 + 31612309 = 31612586
757 + 31611829 = 31612586

Showing the first eight; more decompositions exist.
