Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549206, here are decompositions:

5 + 31549201 = 31549206
23 + 31549183 = 31549206
89 + 31549117 = 31549206
107 + 31549099 = 31549206
163 + 31549043 = 31549206
167 + 31549039 = 31549206
197 + 31549009 = 31549206
223 + 31548983 = 31549206

Showing the first eight; more decompositions exist.
