Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520990, here are decompositions:

23 + 520967 = 520990
47 + 520943 = 520990
101 + 520889 = 520990
137 + 520853 = 520990
149 + 520841 = 520990
227 + 520763 = 520990
269 + 520721 = 520990
311 + 520679 = 520990

Showing the first eight; more decompositions exist.
