Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627016, here are decompositions:

37 + 31626979 = 31627016
73 + 31626943 = 31627016
229 + 31626787 = 31627016
307 + 31626709 = 31627016
349 + 31626667 = 31627016
397 + 31626619 = 31627016
409 + 31626607 = 31627016
523 + 31626493 = 31627016

Showing the first eight; more decompositions exist.
