Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549230, here are decompositions:

23 + 31549207 = 31549230
29 + 31549201 = 31549230
47 + 31549183 = 31549230
113 + 31549117 = 31549230
131 + 31549099 = 31549230
149 + 31549081 = 31549230
179 + 31549051 = 31549230
191 + 31549039 = 31549230

Showing the first eight; more decompositions exist.
