Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520902, here are decompositions:

13 + 520889 = 520902
61 + 520841 = 520902
89 + 520813 = 520902
139 + 520763 = 520902
181 + 520721 = 520902
199 + 520703 = 520902
211 + 520691 = 520902
223 + 520679 = 520902

Showing the first eight; more decompositions exist.
