Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505328, here are decompositions:

7 + 505321 = 505328
97 + 505231 = 505328
127 + 505201 = 505328
199 + 505129 = 505328
211 + 505117 = 505328
277 + 505051 = 505328
337 + 504991 = 505328
457 + 504871 = 505328

Showing the first eight; more decompositions exist.
