Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505456, here are decompositions:

47 + 505409 = 505456
89 + 505367 = 505456
137 + 505319 = 505456
173 + 505283 = 505456
179 + 505277 = 505456
269 + 505187 = 505456
317 + 505139 = 505456
359 + 505097 = 505456

Showing the first eight; more decompositions exist.
