Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549934, here are decompositions:

37 + 31549897 = 31549934
43 + 31549891 = 31549934
61 + 31549873 = 31549934
181 + 31549753 = 31549934
271 + 31549663 = 31549934
337 + 31549597 = 31549934
373 + 31549561 = 31549934
523 + 31549411 = 31549934

Showing the first eight; more decompositions exist.
