Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596340, here are decompositions:

23 + 31596317 = 31596340
29 + 31596311 = 31596340
47 + 31596293 = 31596340
131 + 31596209 = 31596340
197 + 31596143 = 31596340
311 + 31596029 = 31596340
467 + 31595873 = 31596340
509 + 31595831 = 31596340

Showing the first eight; more decompositions exist.
