Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617486, here are decompositions:

29 + 31617457 = 31617486
37 + 31617449 = 31617486
73 + 31617413 = 31617486
79 + 31617407 = 31617486
83 + 31617403 = 31617486
107 + 31617379 = 31617486
113 + 31617373 = 31617486
157 + 31617329 = 31617486

Showing the first eight; more decompositions exist.
