Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612556, here are decompositions:

43 + 31612513 = 31612556
103 + 31612453 = 31612556
127 + 31612429 = 31612556
193 + 31612363 = 31612556
487 + 31612069 = 31612556
673 + 31611883 = 31612556
727 + 31611829 = 31612556
739 + 31611817 = 31612556

Showing the first eight; more decompositions exist.
