Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612562, here are decompositions:

31 + 31612531 = 31612562
109 + 31612453 = 31612562
139 + 31612423 = 31612562
181 + 31612381 = 31612562
193 + 31612369 = 31612562
199 + 31612363 = 31612562
211 + 31612351 = 31612562
733 + 31611829 = 31612562

Showing the first eight; more decompositions exist.
