Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596564, here are decompositions:

11 + 31596553 = 31596564
23 + 31596541 = 31596564
53 + 31596511 = 31596564
67 + 31596497 = 31596564
127 + 31596437 = 31596564
151 + 31596413 = 31596564
163 + 31596401 = 31596564
173 + 31596391 = 31596564

Showing the first eight; more decompositions exist.
