Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549474, here are decompositions:

23 + 31549451 = 31549474
71 + 31549403 = 31549474
83 + 31549391 = 31549474
101 + 31549373 = 31549474
137 + 31549337 = 31549474
197 + 31549277 = 31549474
233 + 31549241 = 31549474
293 + 31549181 = 31549474

Showing the first eight; more decompositions exist.
