Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478428, here are decompositions:

7 + 478421 = 478428
11 + 478417 = 478428
17 + 478411 = 478428
29 + 478399 = 478428
37 + 478391 = 478428
89 + 478339 = 478428
107 + 478321 = 478428
157 + 478271 = 478428

Showing the first eight; more decompositions exist.
