Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528280, here are decompositions:

17 + 528263 = 528280
83 + 528197 = 528280
89 + 528191 = 528280
113 + 528167 = 528280
149 + 528131 = 528280
173 + 528107 = 528280
227 + 528053 = 528280
239 + 528041 = 528280

Showing the first eight; more decompositions exist.
