Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492640, here are decompositions:

11 + 492629 = 492640
23 + 492617 = 492640
53 + 492587 = 492640
89 + 492551 = 492640
149 + 492491 = 492640
173 + 492467 = 492640
227 + 492413 = 492640
251 + 492389 = 492640

Showing the first eight; more decompositions exist.
