Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505148, here are decompositions:

19 + 505129 = 505148
31 + 505117 = 505148
37 + 505111 = 505148
97 + 505051 = 505148
157 + 504991 = 505148
181 + 504967 = 505148
211 + 504937 = 505148
271 + 504877 = 505148

Showing the first eight; more decompositions exist.
