Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627624, here are decompositions:

23 + 31627601 = 31627624
47 + 31627577 = 31627624
113 + 31627511 = 31627624
233 + 31627391 = 31627624
251 + 31627373 = 31627624
491 + 31627133 = 31627624
503 + 31627121 = 31627624
617 + 31627007 = 31627624

Showing the first eight; more decompositions exist.
