Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475840, here are decompositions:

3 + 475837 = 475840
17 + 475823 = 475840
47 + 475793 = 475840
89 + 475751 = 475840
149 + 475691 = 475840
191 + 475649 = 475840
227 + 475613 = 475840
257 + 475583 = 475840

Showing the first eight; more decompositions exist.
