Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470646, here are decompositions:

19 + 470627 = 470646
37 + 470609 = 470646
47 + 470599 = 470646
53 + 470593 = 470646
67 + 470579 = 470646
107 + 470539 = 470646
157 + 470489 = 470646
173 + 470473 = 470646

Showing the first eight; more decompositions exist.
