Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478528, here are decompositions:

5 + 478523 = 478528
47 + 478481 = 478528
101 + 478427 = 478528
107 + 478421 = 478528
137 + 478391 = 478528
257 + 478271 = 478528
269 + 478259 = 478528
359 + 478169 = 478528

Showing the first eight; more decompositions exist.
