Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550174, here are decompositions:

37 + 31550137 = 31550174
43 + 31550131 = 31550174
67 + 31550107 = 31550174
127 + 31550047 = 31550174
193 + 31549981 = 31550174
211 + 31549963 = 31550174
241 + 31549933 = 31550174
277 + 31549897 = 31550174

Showing the first eight; more decompositions exist.
