Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520782, here are decompositions:

19 + 520763 = 520782
23 + 520759 = 520782
61 + 520721 = 520782
79 + 520703 = 520782
83 + 520699 = 520782
103 + 520679 = 520782
149 + 520633 = 520782
151 + 520631 = 520782

Showing the first eight; more decompositions exist.
