Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469644, here are decompositions:

13 + 469631 = 469644
17 + 469627 = 469644
31 + 469613 = 469644
61 + 469583 = 469644
83 + 469561 = 469644
101 + 469543 = 469644
103 + 469541 = 469644
157 + 469487 = 469644

Showing the first eight; more decompositions exist.
