Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549964, here are decompositions:

31 + 31549933 = 31549964
67 + 31549897 = 31549964
73 + 31549891 = 31549964
163 + 31549801 = 31549964
211 + 31549753 = 31549964
367 + 31549597 = 31549964
373 + 31549591 = 31549964
727 + 31549237 = 31549964

Showing the first eight; more decompositions exist.
