Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469720, here are decompositions:

3 + 469717 = 469720
29 + 469691 = 469720
47 + 469673 = 469720
71 + 469649 = 469720
89 + 469631 = 469720
107 + 469613 = 469720
131 + 469589 = 469720
137 + 469583 = 469720

Showing the first eight; more decompositions exist.
