Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505828, here are decompositions:

5 + 505823 = 505828
17 + 505811 = 505828
47 + 505781 = 505828
101 + 505727 = 505828
137 + 505691 = 505828
227 + 505601 = 505828
269 + 505559 = 505828
317 + 505511 = 505828

Showing the first eight; more decompositions exist.
