Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617846, here are decompositions:

19 + 31617827 = 31617846
83 + 31617763 = 31617846
89 + 31617757 = 31617846
149 + 31617697 = 31617846
157 + 31617689 = 31617846
167 + 31617679 = 31617846
173 + 31617673 = 31617846
179 + 31617667 = 31617846

Showing the first eight; more decompositions exist.
