Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505178, here are decompositions:

19 + 505159 = 505178
61 + 505117 = 505178
67 + 505111 = 505178
127 + 505051 = 505178
151 + 505027 = 505178
211 + 504967 = 505178
241 + 504937 = 505178
277 + 504901 = 505178

Showing the first eight; more decompositions exist.
