Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478474, here are decompositions:

23 + 478451 = 478474
41 + 478433 = 478474
47 + 478427 = 478474
53 + 478421 = 478474
71 + 478403 = 478474
83 + 478391 = 478474
131 + 478343 = 478474
233 + 478241 = 478474

Showing the first eight; more decompositions exist.
