Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502816, here are decompositions:

29 + 502787 = 502816
47 + 502769 = 502816
113 + 502703 = 502816
173 + 502643 = 502816
263 + 502553 = 502816
317 + 502499 = 502816
557 + 502259 = 502816
569 + 502247 = 502816

Showing the first eight; more decompositions exist.
