Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617762, here are decompositions:

5 + 31617757 = 31617762
73 + 31617689 = 31617762
83 + 31617679 = 31617762
89 + 31617673 = 31617762
103 + 31617659 = 31617762
131 + 31617631 = 31617762
179 + 31617583 = 31617762
199 + 31617563 = 31617762

Showing the first eight; more decompositions exist.
