Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549334, here are decompositions:

7 + 31549327 = 31549334
97 + 31549237 = 31549334
127 + 31549207 = 31549334
151 + 31549183 = 31549334
283 + 31549051 = 31549334
337 + 31548997 = 31549334
373 + 31548961 = 31549334
463 + 31548871 = 31549334

Showing the first eight; more decompositions exist.
