Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520580, here are decompositions:

13 + 520567 = 520580
31 + 520549 = 520580
157 + 520423 = 520580
199 + 520381 = 520580
211 + 520369 = 520580
223 + 520357 = 520580
241 + 520339 = 520580
271 + 520309 = 520580

Showing the first eight; more decompositions exist.
