Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520818, here are decompositions:

5 + 520813 = 520818
31 + 520787 = 520818
59 + 520759 = 520818
71 + 520747 = 520818
97 + 520721 = 520818
101 + 520717 = 520818
127 + 520691 = 520818
139 + 520679 = 520818

Showing the first eight; more decompositions exist.
