Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519918, here are decompositions:

11 + 519907 = 519918
29 + 519889 = 519918
37 + 519881 = 519918
101 + 519817 = 519918
131 + 519787 = 519918
149 + 519769 = 519918
181 + 519737 = 519918
227 + 519691 = 519918

Showing the first eight; more decompositions exist.
