Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518376, here are decompositions:

127 + 518249 = 518376
137 + 518239 = 518376
139 + 518237 = 518376
167 + 518209 = 518376
197 + 518179 = 518376
223 + 518153 = 518376
239 + 518137 = 518376
263 + 518113 = 518376

Showing the first eight; more decompositions exist.
