Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550046, here are decompositions:

19 + 31550027 = 31550046
67 + 31549979 = 31550046
79 + 31549967 = 31550046
83 + 31549963 = 31550046
113 + 31549933 = 31550046
127 + 31549919 = 31550046
149 + 31549897 = 31550046
167 + 31549879 = 31550046

Showing the first eight; more decompositions exist.
