Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501806, here are decompositions:

3 + 501803 = 501806
37 + 501769 = 501806
103 + 501703 = 501806
229 + 501577 = 501806
313 + 501493 = 501806
379 + 501427 = 501806
397 + 501409 = 501806
439 + 501367 = 501806

Showing the first eight; more decompositions exist.
