Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528556, here are decompositions:

29 + 528527 = 528556
47 + 528509 = 528556
137 + 528419 = 528556
173 + 528383 = 528556
227 + 528329 = 528556
239 + 528317 = 528556
257 + 528299 = 528556
293 + 528263 = 528556

Showing the first eight; more decompositions exist.
