Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608826, here are decompositions:

3 + 31608823 = 31608826
5 + 31608821 = 31608826
47 + 31608779 = 31608826
89 + 31608737 = 31608826
113 + 31608713 = 31608826
239 + 31608587 = 31608826
563 + 31608263 = 31608826
659 + 31608167 = 31608826

Showing the first eight; more decompositions exist.
