Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501656, here are decompositions:

19 + 501637 = 501656
79 + 501577 = 501656
163 + 501493 = 501656
193 + 501463 = 501656
229 + 501427 = 501656
313 + 501343 = 501656
433 + 501223 = 501656
439 + 501217 = 501656

Showing the first eight; more decompositions exist.
