Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500866, here are decompositions:

5 + 500861 = 500866
59 + 500807 = 500866
89 + 500777 = 500866
137 + 500729 = 500866
167 + 500699 = 500866
173 + 500693 = 500866
263 + 500603 = 500866
347 + 500519 = 500866

Showing the first eight; more decompositions exist.
