Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520508, here are decompositions:

61 + 520447 = 520508
97 + 520411 = 520508
127 + 520381 = 520508
139 + 520369 = 520508
151 + 520357 = 520508
199 + 520309 = 520508
211 + 520297 = 520508
229 + 520279 = 520508

Showing the first eight; more decompositions exist.
