Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596636, here are decompositions:

23 + 31596613 = 31596636
53 + 31596583 = 31596636
83 + 31596553 = 31596636
139 + 31596497 = 31596636
163 + 31596473 = 31596636
199 + 31596437 = 31596636
223 + 31596413 = 31596636
233 + 31596403 = 31596636

Showing the first eight; more decompositions exist.
