Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596660, here are decompositions:

23 + 31596637 = 31596660
47 + 31596613 = 31596660
89 + 31596571 = 31596660
107 + 31596553 = 31596660
149 + 31596511 = 31596660
163 + 31596497 = 31596660
223 + 31596437 = 31596660
241 + 31596419 = 31596660

Showing the first eight; more decompositions exist.
