Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505118, here are decompositions:

7 + 505111 = 505118
67 + 505051 = 505118
127 + 504991 = 505118
151 + 504967 = 505118
181 + 504937 = 505118
241 + 504877 = 505118
331 + 504787 = 505118
457 + 504661 = 505118

Showing the first eight; more decompositions exist.
