Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549194, here are decompositions:

11 + 31549183 = 31549194
13 + 31549181 = 31549194
107 + 31549087 = 31549194
113 + 31549081 = 31549194
151 + 31549043 = 31549194
197 + 31548997 = 31549194
211 + 31548983 = 31549194
233 + 31548961 = 31549194

Showing the first eight; more decompositions exist.
