Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549962, here are decompositions:

29 + 31549933 = 31549962
43 + 31549919 = 31549962
71 + 31549891 = 31549962
83 + 31549879 = 31549962
89 + 31549873 = 31549962
163 + 31549799 = 31549962
181 + 31549781 = 31549962
211 + 31549751 = 31549962

Showing the first eight; more decompositions exist.
