Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478540, here are decompositions:

17 + 478523 = 478540
47 + 478493 = 478540
59 + 478481 = 478540
89 + 478451 = 478540
107 + 478433 = 478540
113 + 478427 = 478540
137 + 478403 = 478540
149 + 478391 = 478540

Showing the first eight; more decompositions exist.
