Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627832, here are decompositions:

31 + 31627801 = 31627832
79 + 31627753 = 31627832
193 + 31627639 = 31627832
331 + 31627501 = 31627832
349 + 31627483 = 31627832
421 + 31627411 = 31627832
499 + 31627333 = 31627832
571 + 31627261 = 31627832

Showing the first eight; more decompositions exist.
