Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617532, here are decompositions:

3 + 31617529 = 31617532
29 + 31617503 = 31617532
71 + 31617461 = 31617532
83 + 31617449 = 31617532
101 + 31617431 = 31617532
239 + 31617293 = 31617532
251 + 31617281 = 31617532
263 + 31617269 = 31617532

Showing the first eight; more decompositions exist.
