Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502820, here are decompositions:

13 + 502807 = 502820
103 + 502717 = 502820
151 + 502669 = 502820
223 + 502597 = 502820
229 + 502591 = 502820
271 + 502549 = 502820
277 + 502543 = 502820
313 + 502507 = 502820

Showing the first eight; more decompositions exist.
