Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596386, here are decompositions:

7 + 31596379 = 31596386
79 + 31596307 = 31596386
193 + 31596193 = 31596386
223 + 31596163 = 31596386
337 + 31596049 = 31596386
379 + 31596007 = 31596386
397 + 31595989 = 31596386
457 + 31595929 = 31596386

Showing the first eight; more decompositions exist.
