Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505944, here are decompositions:

17 + 505927 = 505944
37 + 505907 = 505944
67 + 505877 = 505944
73 + 505871 = 505944
163 + 505781 = 505944
167 + 505777 = 505944
181 + 505763 = 505944
233 + 505711 = 505944

Showing the first eight; more decompositions exist.
