Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469918, here are decompositions:

11 + 469907 = 469918
41 + 469877 = 469918
107 + 469811 = 469918
131 + 469787 = 469918
149 + 469769 = 469918
227 + 469691 = 469918
269 + 469649 = 469918
389 + 469529 = 469918

Showing the first eight; more decompositions exist.
