Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627826, here are decompositions:

73 + 31627753 = 31627826
199 + 31627627 = 31627826
283 + 31627543 = 31627826
523 + 31627303 = 31627826
577 + 31627249 = 31627826
757 + 31627069 = 31627826
859 + 31626967 = 31627826
883 + 31626943 = 31627826

Showing the first eight; more decompositions exist.
