Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520806, here are decompositions:

19 + 520787 = 520806
43 + 520763 = 520806
47 + 520759 = 520806
59 + 520747 = 520806
89 + 520717 = 520806
103 + 520703 = 520806
107 + 520699 = 520806
127 + 520679 = 520806

Showing the first eight; more decompositions exist.
