Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550068, here are decompositions:

5 + 31550063 = 31550068
41 + 31550027 = 31550068
47 + 31550021 = 31550068
89 + 31549979 = 31550068
101 + 31549967 = 31550068
149 + 31549919 = 31550068
239 + 31549829 = 31550068
269 + 31549799 = 31550068

Showing the first eight; more decompositions exist.
