Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549248, here are decompositions:

7 + 31549241 = 31549248
11 + 31549237 = 31549248
41 + 31549207 = 31549248
47 + 31549201 = 31549248
67 + 31549181 = 31549248
131 + 31549117 = 31549248
149 + 31549099 = 31549248
167 + 31549081 = 31549248

Showing the first eight; more decompositions exist.
