Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596748, here are decompositions:

5 + 31596743 = 31596748
41 + 31596707 = 31596748
137 + 31596611 = 31596748
251 + 31596497 = 31596748
311 + 31596437 = 31596748
347 + 31596401 = 31596748
431 + 31596317 = 31596748
719 + 31596029 = 31596748

Showing the first eight; more decompositions exist.
