Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550698, here are decompositions:

17 + 31550681 = 31550698
71 + 31550627 = 31550698
167 + 31550531 = 31550698
227 + 31550471 = 31550698
239 + 31550459 = 31550698
251 + 31550447 = 31550698
359 + 31550339 = 31550698
521 + 31550177 = 31550698

Showing the first eight; more decompositions exist.
