Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550334, here are decompositions:

5 + 31550329 = 31550334
7 + 31550327 = 31550334
47 + 31550287 = 31550334
83 + 31550251 = 31550334
113 + 31550221 = 31550334
157 + 31550177 = 31550334
181 + 31550153 = 31550334
197 + 31550137 = 31550334

Showing the first eight; more decompositions exist.
