Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529528, here are decompositions:

11 + 529517 = 529528
107 + 529421 = 529528
179 + 529349 = 529528
227 + 529301 = 529528
257 + 529271 = 529528
269 + 529259 = 529528
347 + 529181 = 529528
401 + 529127 = 529528

Showing the first eight; more decompositions exist.
