Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505272, here are decompositions:

41 + 505231 = 505272
59 + 505213 = 505272
71 + 505201 = 505272
113 + 505159 = 505272
149 + 505123 = 505272
181 + 505091 = 505272
199 + 505073 = 505272
211 + 505061 = 505272

Showing the first eight; more decompositions exist.
