Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468474, here are decompositions:

3 + 31468471 = 31468474
71 + 31468403 = 31468474
83 + 31468391 = 31468474
137 + 31468337 = 31468474
227 + 31468247 = 31468474
251 + 31468223 = 31468474
263 + 31468211 = 31468474
461 + 31468013 = 31468474

Showing the first eight; more decompositions exist.
