Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550060, here are decompositions:

13 + 31550047 = 31550060
79 + 31549981 = 31550060
97 + 31549963 = 31550060
127 + 31549933 = 31550060
163 + 31549897 = 31550060
181 + 31549879 = 31550060
307 + 31549753 = 31550060
331 + 31549729 = 31550060

Showing the first eight; more decompositions exist.
