Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608652, here are decompositions:

311 + 31608341 = 31608652
389 + 31608263 = 31608652
503 + 31608149 = 31608652
521 + 31608131 = 31608652
683 + 31607969 = 31608652
743 + 31607909 = 31608652
821 + 31607831 = 31608652
863 + 31607789 = 31608652

Showing the first eight; more decompositions exist.
