Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549476, here are decompositions:

37 + 31549439 = 31549476
73 + 31549403 = 31549476
103 + 31549373 = 31549476
137 + 31549339 = 31549476
139 + 31549337 = 31549476
149 + 31549327 = 31549476
199 + 31549277 = 31549476
239 + 31549237 = 31549476

Showing the first eight; more decompositions exist.
