Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627432, here are decompositions:

41 + 31627391 = 31627432
59 + 31627373 = 31627432
113 + 31627319 = 31627432
281 + 31627151 = 31627432
311 + 31627121 = 31627432
359 + 31627073 = 31627432
563 + 31626869 = 31627432
593 + 31626839 = 31627432

Showing the first eight; more decompositions exist.
