Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518356, here are decompositions:

29 + 518327 = 518356
107 + 518249 = 518356
149 + 518207 = 518356
197 + 518159 = 518356
227 + 518129 = 518356
233 + 518123 = 518356
257 + 518099 = 518356
389 + 517967 = 518356

Showing the first eight; more decompositions exist.
