Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469666, here are decompositions:

17 + 469649 = 469666
53 + 469613 = 469666
83 + 469583 = 469666
137 + 469529 = 469666
179 + 469487 = 469666
227 + 469439 = 469666
269 + 469397 = 469666
383 + 469283 = 469666

Showing the first eight; more decompositions exist.
