Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518324, here are decompositions:

13 + 518311 = 518324
193 + 518131 = 518324
211 + 518113 = 518324
223 + 518101 = 518324
241 + 518083 = 518324
277 + 518047 = 518324
307 + 518017 = 518324
397 + 517927 = 518324

Showing the first eight; more decompositions exist.
