Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520876, here are decompositions:

23 + 520853 = 520876
89 + 520787 = 520876
113 + 520763 = 520876
173 + 520703 = 520876
197 + 520679 = 520876
227 + 520649 = 520876
269 + 520607 = 520876
347 + 520529 = 520876

Showing the first eight; more decompositions exist.
