Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475640, here are decompositions:

3 + 475637 = 475640
19 + 475621 = 475640
43 + 475597 = 475640
157 + 475483 = 475640
199 + 475441 = 475640
211 + 475429 = 475640
223 + 475417 = 475640
271 + 475369 = 475640

Showing the first eight; more decompositions exist.
