Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501686, here are decompositions:

109 + 501577 = 501686
193 + 501493 = 501686
223 + 501463 = 501686
277 + 501409 = 501686
457 + 501229 = 501686
463 + 501223 = 501686
499 + 501187 = 501686
547 + 501139 = 501686

Showing the first eight; more decompositions exist.
