Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478018, here are decompositions:

17 + 478001 = 478018
41 + 477977 = 478018
71 + 477947 = 478018
137 + 477881 = 478018
179 + 477839 = 478018
197 + 477821 = 478018
227 + 477791 = 478018
251 + 477767 = 478018

Showing the first eight; more decompositions exist.
