Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475440, here are decompositions:

11 + 475429 = 475440
13 + 475427 = 475440
19 + 475421 = 475440
23 + 475417 = 475440
37 + 475403 = 475440
59 + 475381 = 475440
61 + 475379 = 475440
71 + 475369 = 475440

Showing the first eight; more decompositions exist.
