Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550344, here are decompositions:

5 + 31550339 = 31550344
17 + 31550327 = 31550344
131 + 31550213 = 31550344
167 + 31550177 = 31550344
191 + 31550153 = 31550344
233 + 31550111 = 31550344
251 + 31550093 = 31550344
281 + 31550063 = 31550344

Showing the first eight; more decompositions exist.
