Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627448, here are decompositions:

37 + 31627411 = 31627448
199 + 31627249 = 31627448
211 + 31627237 = 31627448
379 + 31627069 = 31627448
397 + 31627051 = 31627448
421 + 31627027 = 31627448
607 + 31626841 = 31627448
661 + 31626787 = 31627448

Showing the first eight; more decompositions exist.
