Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505124, here are decompositions:

7 + 505117 = 505124
13 + 505111 = 505124
73 + 505051 = 505124
97 + 505027 = 505124
157 + 504967 = 505124
181 + 504943 = 505124
223 + 504901 = 505124
271 + 504853 = 505124

Showing the first eight; more decompositions exist.
