Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612826, here are decompositions:

67 + 31612759 = 31612826
73 + 31612753 = 31612826
79 + 31612747 = 31612826
97 + 31612729 = 31612826
163 + 31612663 = 31612826
199 + 31612627 = 31612826
229 + 31612597 = 31612826
313 + 31612513 = 31612826

Showing the first eight; more decompositions exist.
