Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612528, here are decompositions:

41 + 31612487 = 31612528
47 + 31612481 = 31612528
137 + 31612391 = 31612528
251 + 31612277 = 31612528
419 + 31612109 = 31612528
449 + 31612079 = 31612528
587 + 31611941 = 31612528
617 + 31611911 = 31612528

Showing the first eight; more decompositions exist.
