Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612832, here are decompositions:

73 + 31612759 = 31612832
79 + 31612753 = 31612832
103 + 31612729 = 31612832
211 + 31612621 = 31612832
379 + 31612453 = 31612832
409 + 31612423 = 31612832
463 + 31612369 = 31612832
523 + 31612309 = 31612832

Showing the first eight; more decompositions exist.
