Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596326, here are decompositions:

19 + 31596307 = 31596326
163 + 31596163 = 31596326
199 + 31596127 = 31596326
277 + 31596049 = 31596326
337 + 31595989 = 31596326
397 + 31595929 = 31596326
457 + 31595869 = 31596326
607 + 31595719 = 31596326

Showing the first eight; more decompositions exist.
