Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469686, here are decompositions:

13 + 469673 = 469686
29 + 469657 = 469686
37 + 469649 = 469686
59 + 469627 = 469686
73 + 469613 = 469686
97 + 469589 = 469686
103 + 469583 = 469686
157 + 469529 = 469686

Showing the first eight; more decompositions exist.
