Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475638, here are decompositions:

17 + 475621 = 475638
19 + 475619 = 475638
41 + 475597 = 475638
89 + 475549 = 475638
109 + 475529 = 475638
127 + 475511 = 475638
181 + 475457 = 475638
197 + 475441 = 475638

Showing the first eight; more decompositions exist.
