Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518512, here are decompositions:

3 + 518509 = 518512
41 + 518471 = 518512
83 + 518429 = 518512
101 + 518411 = 518512
251 + 518261 = 518512
263 + 518249 = 518512
353 + 518159 = 518512
359 + 518153 = 518512

Showing the first eight; more decompositions exist.
