Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505116, here are decompositions:

5 + 505111 = 505116
19 + 505097 = 505116
43 + 505073 = 505116
67 + 505049 = 505116
83 + 505033 = 505116
89 + 505027 = 505116
127 + 504989 = 505116
149 + 504967 = 505116

Showing the first eight; more decompositions exist.
