Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549332, here are decompositions:

5 + 31549327 = 31549332
131 + 31549201 = 31549332
149 + 31549183 = 31549332
151 + 31549181 = 31549332
233 + 31549099 = 31549332
251 + 31549081 = 31549332
281 + 31549051 = 31549332
293 + 31549039 = 31549332

Showing the first eight; more decompositions exist.
