Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550194, here are decompositions:

17 + 31550177 = 31550194
41 + 31550153 = 31550194
83 + 31550111 = 31550194
101 + 31550093 = 31550194
131 + 31550063 = 31550194
167 + 31550027 = 31550194
173 + 31550021 = 31550194
227 + 31549967 = 31550194

Showing the first eight; more decompositions exist.
