Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520900, here are decompositions:

11 + 520889 = 520900
47 + 520853 = 520900
59 + 520841 = 520900
113 + 520787 = 520900
137 + 520763 = 520900
179 + 520721 = 520900
197 + 520703 = 520900
251 + 520649 = 520900

Showing the first eight; more decompositions exist.
