Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550058, here are decompositions:

11 + 31550047 = 31550058
31 + 31550027 = 31550058
37 + 31550021 = 31550058
79 + 31549979 = 31550058
139 + 31549919 = 31550058
167 + 31549891 = 31550058
179 + 31549879 = 31550058
229 + 31549829 = 31550058

Showing the first eight; more decompositions exist.
