Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550064, here are decompositions:

17 + 31550047 = 31550064
37 + 31550027 = 31550064
43 + 31550021 = 31550064
83 + 31549981 = 31550064
97 + 31549967 = 31550064
101 + 31549963 = 31550064
131 + 31549933 = 31550064
167 + 31549897 = 31550064

Showing the first eight; more decompositions exist.
