Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549944, here are decompositions:

11 + 31549933 = 31549944
47 + 31549897 = 31549944
53 + 31549891 = 31549944
71 + 31549873 = 31549944
163 + 31549781 = 31549944
191 + 31549753 = 31549944
193 + 31549751 = 31549944
211 + 31549733 = 31549944

Showing the first eight; more decompositions exist.
