Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469840, here are decompositions:

17 + 469823 = 469840
29 + 469811 = 469840
47 + 469793 = 469840
53 + 469787 = 469840
71 + 469769 = 469840
83 + 469757 = 469840
149 + 469691 = 469840
167 + 469673 = 469840

Showing the first eight; more decompositions exist.
