Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510918, here are decompositions:

11 + 510907 = 510918
29 + 510889 = 510918
71 + 510847 = 510918
101 + 510817 = 510918
151 + 510767 = 510918
167 + 510751 = 510918
211 + 510707 = 510918
227 + 510691 = 510918

Showing the first eight; more decompositions exist.
