Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506728, here are decompositions:

29 + 506699 = 506728
41 + 506687 = 506728
137 + 506591 = 506728
191 + 506537 = 506728
197 + 506531 = 506728
227 + 506501 = 506728
269 + 506459 = 506728
311 + 506417 = 506728

Showing the first eight; more decompositions exist.
