Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518386, here are decompositions:

59 + 518327 = 518386
137 + 518249 = 518386
149 + 518237 = 518386
179 + 518207 = 518386
227 + 518159 = 518386
233 + 518153 = 518386
257 + 518129 = 518386
263 + 518123 = 518386

Showing the first eight; more decompositions exist.
