Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505166, here are decompositions:

7 + 505159 = 505166
37 + 505129 = 505166
43 + 505123 = 505166
139 + 505027 = 505166
199 + 504967 = 505166
223 + 504943 = 505166
229 + 504937 = 505166
313 + 504853 = 505166

Showing the first eight; more decompositions exist.
