Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518278, here are decompositions:

17 + 518261 = 518278
29 + 518249 = 518278
41 + 518237 = 518278
71 + 518207 = 518278
107 + 518171 = 518278
149 + 518129 = 518278
179 + 518099 = 518278
311 + 517967 = 518278

Showing the first eight; more decompositions exist.
