Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612406, here are decompositions:

37 + 31612369 = 31612406
43 + 31612363 = 31612406
97 + 31612309 = 31612406
337 + 31612069 = 31612406
409 + 31611997 = 31612406
499 + 31611907 = 31612406
523 + 31611883 = 31612406
577 + 31611829 = 31612406

Showing the first eight; more decompositions exist.
