Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617774, here are decompositions:

11 + 31617763 = 31617774
17 + 31617757 = 31617774
61 + 31617713 = 31617774
101 + 31617673 = 31617774
107 + 31617667 = 31617774
191 + 31617583 = 31617774
211 + 31617563 = 31617774
241 + 31617533 = 31617774

Showing the first eight; more decompositions exist.
