Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501866, here are decompositions:

3 + 501863 = 501866
37 + 501829 = 501866
97 + 501769 = 501866
163 + 501703 = 501866
229 + 501637 = 501866
373 + 501493 = 501866
439 + 501427 = 501866
457 + 501409 = 501866

Showing the first eight; more decompositions exist.
