Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528664, here are decompositions:

5 + 528659 = 528664
41 + 528623 = 528664
53 + 528611 = 528664
137 + 528527 = 528664
173 + 528491 = 528664
251 + 528413 = 528664
263 + 528401 = 528664
281 + 528383 = 528664

Showing the first eight; more decompositions exist.
