Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501566, here are decompositions:

3 + 501563 = 501566
73 + 501493 = 501566
103 + 501463 = 501566
139 + 501427 = 501566
157 + 501409 = 501566
199 + 501367 = 501566
223 + 501343 = 501566
337 + 501229 = 501566

Showing the first eight; more decompositions exist.
