Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617944, here are decompositions:

3 + 31617941 = 31617944
67 + 31617877 = 31617944
73 + 31617871 = 31617944
181 + 31617763 = 31617944
271 + 31617673 = 31617944
277 + 31617667 = 31617944
313 + 31617631 = 31617944
487 + 31617457 = 31617944

Showing the first eight; more decompositions exist.
