Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505384, here are decompositions:

17 + 505367 = 505384
71 + 505313 = 505384
83 + 505301 = 505384
101 + 505283 = 505384
107 + 505277 = 505384
197 + 505187 = 505384
227 + 505157 = 505384
293 + 505091 = 505384

Showing the first eight; more decompositions exist.
