Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502666, here are decompositions:

23 + 502643 = 502666
53 + 502613 = 502666
113 + 502553 = 502666
149 + 502517 = 502666
167 + 502499 = 502666
179 + 502487 = 502666
257 + 502409 = 502666
389 + 502277 = 502666

Showing the first eight; more decompositions exist.
