Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518286, here are decompositions:

37 + 518249 = 518286
47 + 518239 = 518286
53 + 518233 = 518286
79 + 518207 = 518286
107 + 518179 = 518286
127 + 518159 = 518286
149 + 518137 = 518286
157 + 518129 = 518286

Showing the first eight; more decompositions exist.
