Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627238, here are decompositions:

37 + 31627201 = 31627238
211 + 31627027 = 31627238
271 + 31626967 = 31627238
397 + 31626841 = 31627238
547 + 31626691 = 31627238
571 + 31626667 = 31627238
619 + 31626619 = 31627238
631 + 31626607 = 31627238

Showing the first eight; more decompositions exist.
