Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470688, here are decompositions:

19 + 470669 = 470688
37 + 470651 = 470688
41 + 470647 = 470688
61 + 470627 = 470688
67 + 470621 = 470688
79 + 470609 = 470688
89 + 470599 = 470688
109 + 470579 = 470688

Showing the first eight; more decompositions exist.
