Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596938, here are decompositions:

31 + 31596907 = 31596938
181 + 31596757 = 31596938
229 + 31596709 = 31596938
277 + 31596661 = 31596938
367 + 31596571 = 31596938
397 + 31596541 = 31596938
547 + 31596391 = 31596938
631 + 31596307 = 31596938

Showing the first eight; more decompositions exist.
