Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617946, here are decompositions:

5 + 31617941 = 31617946
47 + 31617899 = 31617946
83 + 31617863 = 31617946
149 + 31617797 = 31617946
233 + 31617713 = 31617946
257 + 31617689 = 31617946
317 + 31617629 = 31617946
359 + 31617587 = 31617946

Showing the first eight; more decompositions exist.
