Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475666, here are decompositions:

17 + 475649 = 475666
29 + 475637 = 475666
47 + 475619 = 475666
53 + 475613 = 475666
83 + 475583 = 475666
137 + 475529 = 475666
197 + 475469 = 475666
239 + 475427 = 475666

Showing the first eight; more decompositions exist.
