Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518676, here are decompositions:

19 + 518657 = 518676
79 + 518597 = 518676
89 + 518587 = 518676
97 + 518579 = 518676
167 + 518509 = 518676
229 + 518447 = 518676
349 + 518327 = 518676
439 + 518237 = 518676

Showing the first eight; more decompositions exist.
