Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520918, here are decompositions:

5 + 520913 = 520918
29 + 520889 = 520918
131 + 520787 = 520918
197 + 520721 = 520918
227 + 520691 = 520918
239 + 520679 = 520918
269 + 520649 = 520918
311 + 520607 = 520918

Showing the first eight; more decompositions exist.
