Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549952, here are decompositions:

19 + 31549933 = 31549952
61 + 31549891 = 31549952
73 + 31549879 = 31549952
79 + 31549873 = 31549952
151 + 31549801 = 31549952
199 + 31549753 = 31549952
223 + 31549729 = 31549952
373 + 31549579 = 31549952

Showing the first eight; more decompositions exist.
