Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550200, here are decompositions:

23 + 31550177 = 31550200
47 + 31550153 = 31550200
89 + 31550111 = 31550200
107 + 31550093 = 31550200
137 + 31550063 = 31550200
173 + 31550027 = 31550200
179 + 31550021 = 31550200
233 + 31549967 = 31550200

Showing the first eight; more decompositions exist.
