Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469866, here are decompositions:

17 + 469849 = 469866
43 + 469823 = 469866
73 + 469793 = 469866
79 + 469787 = 469866
97 + 469769 = 469866
109 + 469757 = 469866
113 + 469753 = 469866
149 + 469717 = 469866

Showing the first eight; more decompositions exist.
