Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550266, here are decompositions:

53 + 31550213 = 31550266
89 + 31550177 = 31550266
113 + 31550153 = 31550266
173 + 31550093 = 31550266
239 + 31550027 = 31550266
347 + 31549919 = 31550266
467 + 31549799 = 31550266
599 + 31549667 = 31550266

Showing the first eight; more decompositions exist.
