Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470666, here are decompositions:

3 + 470663 = 470666
13 + 470653 = 470666
19 + 470647 = 470666
67 + 470599 = 470666
73 + 470593 = 470666
127 + 470539 = 470666
193 + 470473 = 470666
223 + 470443 = 470666

Showing the first eight; more decompositions exist.
