Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478480, here are decompositions:

29 + 478451 = 478480
47 + 478433 = 478480
53 + 478427 = 478480
59 + 478421 = 478480
89 + 478391 = 478480
137 + 478343 = 478480
227 + 478253 = 478480
239 + 478241 = 478480

Showing the first eight; more decompositions exist.
