Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501556, here are decompositions:

53 + 501503 = 501556
137 + 501419 = 501556
173 + 501383 = 501556
239 + 501317 = 501556
257 + 501299 = 501556
269 + 501287 = 501556
347 + 501209 = 501556
353 + 501203 = 501556

Showing the first eight; more decompositions exist.
