Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549510, here are decompositions:

11 + 31549499 = 31549510
59 + 31549451 = 31549510
71 + 31549439 = 31549510
107 + 31549403 = 31549510
137 + 31549373 = 31549510
173 + 31549337 = 31549510
233 + 31549277 = 31549510
269 + 31549241 = 31549510

Showing the first eight; more decompositions exist.
