Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505528, here are decompositions:

5 + 505523 = 505528
17 + 505511 = 505528
47 + 505481 = 505528
59 + 505469 = 505528
227 + 505301 = 505528
251 + 505277 = 505528
347 + 505181 = 505528
389 + 505139 = 505528

Showing the first eight; more decompositions exist.
