Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502866, here are decompositions:

5 + 502861 = 502866
19 + 502847 = 502866
37 + 502829 = 502866
47 + 502819 = 502866
59 + 502807 = 502866
79 + 502787 = 502866
97 + 502769 = 502866
137 + 502729 = 502866

Showing the first eight; more decompositions exist.
