Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520910, here are decompositions:

43 + 520867 = 520910
73 + 520837 = 520910
97 + 520813 = 520910
151 + 520759 = 520910
163 + 520747 = 520910
193 + 520717 = 520910
211 + 520699 = 520910
277 + 520633 = 520910

Showing the first eight; more decompositions exist.
