Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627382, here are decompositions:

79 + 31627303 = 31627382
139 + 31627243 = 31627382
181 + 31627201 = 31627382
313 + 31627069 = 31627382
331 + 31627051 = 31627382
349 + 31627033 = 31627382
439 + 31626943 = 31627382
499 + 31626883 = 31627382

Showing the first eight; more decompositions exist.
