Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617982, here are decompositions:

23 + 31617959 = 31617982
29 + 31617953 = 31617982
41 + 31617941 = 31617982
83 + 31617899 = 31617982
269 + 31617713 = 31617982
293 + 31617689 = 31617982
353 + 31617629 = 31617982
419 + 31617563 = 31617982

Showing the first eight; more decompositions exist.
