Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549506, here are decompositions:

7 + 31549499 = 31549506
67 + 31549439 = 31549506
103 + 31549403 = 31549506
167 + 31549339 = 31549506
179 + 31549327 = 31549506
229 + 31549277 = 31549506
269 + 31549237 = 31549506
389 + 31549117 = 31549506

Showing the first eight; more decompositions exist.
