Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549176, here are decompositions:

59 + 31549117 = 31549176
89 + 31549087 = 31549176
137 + 31549039 = 31549176
157 + 31549019 = 31549176
167 + 31549009 = 31549176
179 + 31548997 = 31549176
193 + 31548983 = 31549176
223 + 31548953 = 31549176

Showing the first eight; more decompositions exist.
