Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505238, here are decompositions:

7 + 505231 = 505238
37 + 505201 = 505238
79 + 505159 = 505238
109 + 505129 = 505238
127 + 505111 = 505238
211 + 505027 = 505238
271 + 504967 = 505238
337 + 504901 = 505238

Showing the first eight; more decompositions exist.
