Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479540, here are decompositions:

7 + 479533 = 479540
31 + 479509 = 479540
43 + 479497 = 479540
67 + 479473 = 479540
79 + 479461 = 479540
109 + 479431 = 479540
163 + 479377 = 479540
223 + 479317 = 479540

Showing the first eight; more decompositions exist.
