Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470660, here are decompositions:

7 + 470653 = 470660
13 + 470647 = 470660
61 + 470599 = 470660
67 + 470593 = 470660
109 + 470551 = 470660
139 + 470521 = 470660
199 + 470461 = 470660
271 + 470389 = 470660

Showing the first eight; more decompositions exist.
