Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627958, here are decompositions:

31 + 31627927 = 31627958
79 + 31627879 = 31627958
97 + 31627861 = 31627958
157 + 31627801 = 31627958
331 + 31627627 = 31627958
421 + 31627537 = 31627958
457 + 31627501 = 31627958
547 + 31627411 = 31627958

Showing the first eight; more decompositions exist.
