Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612376, here are decompositions:

7 + 31612369 = 31612376
13 + 31612363 = 31612376
67 + 31612309 = 31612376
307 + 31612069 = 31612376
379 + 31611997 = 31612376
547 + 31611829 = 31612376
619 + 31611757 = 31612376
643 + 31611733 = 31612376

Showing the first eight; more decompositions exist.
