Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505266, here are decompositions:

29 + 505237 = 505266
53 + 505213 = 505266
79 + 505187 = 505266
107 + 505159 = 505266
109 + 505157 = 505266
127 + 505139 = 505266
137 + 505129 = 505266
149 + 505117 = 505266

Showing the first eight; more decompositions exist.
