Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518306, here are decompositions:

7 + 518299 = 518306
67 + 518239 = 518306
73 + 518233 = 518306
97 + 518209 = 518306
127 + 518179 = 518306
193 + 518113 = 518306
223 + 518083 = 518306
307 + 517999 = 518306

Showing the first eight; more decompositions exist.
