Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478498, here are decompositions:

5 + 478493 = 478498
17 + 478481 = 478498
47 + 478451 = 478498
71 + 478427 = 478498
107 + 478391 = 478498
227 + 478271 = 478498
239 + 478259 = 478498
257 + 478241 = 478498

Showing the first eight; more decompositions exist.
