Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490474, here are decompositions:

11 + 490463 = 490474
53 + 490421 = 490474
107 + 490367 = 490474
191 + 490283 = 490474
197 + 490277 = 490474
227 + 490247 = 490474
233 + 490241 = 490474
251 + 490223 = 490474

Showing the first eight; more decompositions exist.
