Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505188, here are decompositions:

7 + 505181 = 505188
29 + 505159 = 505188
31 + 505157 = 505188
59 + 505129 = 505188
71 + 505117 = 505188
97 + 505091 = 505188
127 + 505061 = 505188
137 + 505051 = 505188

Showing the first eight; more decompositions exist.
