Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612472, here are decompositions:

19 + 31612453 = 31612472
43 + 31612429 = 31612472
103 + 31612369 = 31612472
109 + 31612363 = 31612472
163 + 31612309 = 31612472
271 + 31612201 = 31612472
631 + 31611841 = 31612472
643 + 31611829 = 31612472

Showing the first eight; more decompositions exist.
