Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520804, here are decompositions:

17 + 520787 = 520804
41 + 520763 = 520804
83 + 520721 = 520804
101 + 520703 = 520804
113 + 520691 = 520804
173 + 520631 = 520804
197 + 520607 = 520804
233 + 520571 = 520804

Showing the first eight; more decompositions exist.
