Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502518, here are decompositions:

11 + 502507 = 502518
17 + 502501 = 502518
19 + 502499 = 502518
31 + 502487 = 502518
67 + 502451 = 502518
89 + 502429 = 502518
97 + 502421 = 502518
109 + 502409 = 502518

Showing the first eight; more decompositions exist.
