Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550182, here are decompositions:

3 + 31550179 = 31550182
5 + 31550177 = 31550182
29 + 31550153 = 31550182
71 + 31550111 = 31550182
89 + 31550093 = 31550182
263 + 31549919 = 31550182
353 + 31549829 = 31550182
383 + 31549799 = 31550182

Showing the first eight; more decompositions exist.
