Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549368, here are decompositions:

29 + 31549339 = 31549368
31 + 31549337 = 31549368
41 + 31549327 = 31549368
127 + 31549241 = 31549368
131 + 31549237 = 31549368
167 + 31549201 = 31549368
251 + 31549117 = 31549368
269 + 31549099 = 31549368

Showing the first eight; more decompositions exist.
