Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518918, here are decompositions:

7 + 518911 = 518918
109 + 518809 = 518918
139 + 518779 = 518918
151 + 518767 = 518918
157 + 518761 = 518918
181 + 518737 = 518918
229 + 518689 = 518918
307 + 518611 = 518918

Showing the first eight; more decompositions exist.
