Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612636, here are decompositions:

17 + 31612619 = 31612636
47 + 31612589 = 31612636
53 + 31612583 = 31612636
89 + 31612547 = 31612636
149 + 31612487 = 31612636
359 + 31612277 = 31612636
557 + 31612079 = 31612636
593 + 31612043 = 31612636

Showing the first eight; more decompositions exist.
