Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617588, here are decompositions:

5 + 31617583 = 31617588
29 + 31617559 = 31617588
59 + 31617529 = 31617588
127 + 31617461 = 31617588
131 + 31617457 = 31617588
139 + 31617449 = 31617588
157 + 31617431 = 31617588
179 + 31617409 = 31617588

Showing the first eight; more decompositions exist.
