Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502420, here are decompositions:

11 + 502409 = 502420
173 + 502247 = 502420
239 + 502181 = 502420
419 + 502001 = 502420
449 + 501971 = 502420
467 + 501953 = 502420
509 + 501911 = 502420
557 + 501863 = 502420

Showing the first eight; more decompositions exist.
