Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505366, here are decompositions:

47 + 505319 = 505366
53 + 505313 = 505366
83 + 505283 = 505366
89 + 505277 = 505366
179 + 505187 = 505366
227 + 505139 = 505366
269 + 505097 = 505366
293 + 505073 = 505366

Showing the first eight; more decompositions exist.
