Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520810, here are decompositions:

23 + 520787 = 520810
47 + 520763 = 520810
89 + 520721 = 520810
107 + 520703 = 520810
131 + 520679 = 520810
179 + 520631 = 520810
239 + 520571 = 520810
263 + 520547 = 520810

Showing the first eight; more decompositions exist.
