Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469828, here are decompositions:

5 + 469823 = 469828
17 + 469811 = 469828
41 + 469787 = 469828
59 + 469769 = 469828
71 + 469757 = 469828
137 + 469691 = 469828
179 + 469649 = 469828
197 + 469631 = 469828

Showing the first eight; more decompositions exist.
