Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520816, here are decompositions:

3 + 520813 = 520816
29 + 520787 = 520816
53 + 520763 = 520816
113 + 520703 = 520816
137 + 520679 = 520816
167 + 520649 = 520816
227 + 520589 = 520816
269 + 520547 = 520816

Showing the first eight; more decompositions exist.
