Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518360, here are decompositions:

19 + 518341 = 518360
61 + 518299 = 518360
127 + 518233 = 518360
151 + 518209 = 518360
181 + 518179 = 518360
223 + 518137 = 518360
229 + 518131 = 518360
277 + 518083 = 518360

Showing the first eight; more decompositions exist.
