Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505736, here are decompositions:

43 + 505693 = 505736
67 + 505669 = 505736
73 + 505663 = 505736
79 + 505657 = 505736
97 + 505639 = 505736
103 + 505633 = 505736
163 + 505573 = 505736
199 + 505537 = 505736

Showing the first eight; more decompositions exist.
