Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518258, here are decompositions:

19 + 518239 = 518258
67 + 518191 = 518258
79 + 518179 = 518258
127 + 518131 = 518258
157 + 518101 = 518258
199 + 518059 = 518258
211 + 518047 = 518258
241 + 518017 = 518258

Showing the first eight; more decompositions exist.
