Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518888, here are decompositions:

79 + 518809 = 518888
109 + 518779 = 518888
127 + 518761 = 518888
151 + 518737 = 518888
199 + 518689 = 518888
277 + 518611 = 518888
367 + 518521 = 518888
379 + 518509 = 518888

Showing the first eight; more decompositions exist.
