Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596728, here are decompositions:

19 + 31596709 = 31596728
67 + 31596661 = 31596728
157 + 31596571 = 31596728
337 + 31596391 = 31596728
349 + 31596379 = 31596728
421 + 31596307 = 31596728
577 + 31596151 = 31596728
601 + 31596127 = 31596728

Showing the first eight; more decompositions exist.
