Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518636, here are decompositions:

103 + 518533 = 518636
127 + 518509 = 518636
163 + 518473 = 518636
337 + 518299 = 518636
397 + 518239 = 518636
457 + 518179 = 518636
499 + 518137 = 518636
523 + 518113 = 518636

Showing the first eight; more decompositions exist.
