Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528544, here are decompositions:

17 + 528527 = 528544
53 + 528491 = 528544
131 + 528413 = 528544
227 + 528317 = 528544
281 + 528263 = 528544
347 + 528197 = 528544
353 + 528191 = 528544
491 + 528053 = 528544

Showing the first eight; more decompositions exist.
