Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550052, here are decompositions:

5 + 31550047 = 31550052
31 + 31550021 = 31550052
71 + 31549981 = 31550052
73 + 31549979 = 31550052
89 + 31549963 = 31550052
173 + 31549879 = 31550052
179 + 31549873 = 31550052
223 + 31549829 = 31550052

Showing the first eight; more decompositions exist.
