Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475488, here are decompositions:

5 + 475483 = 475488
19 + 475469 = 475488
31 + 475457 = 475488
47 + 475441 = 475488
59 + 475429 = 475488
61 + 475427 = 475488
67 + 475421 = 475488
71 + 475417 = 475488

Showing the first eight; more decompositions exist.
