Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528208, here are decompositions:

11 + 528197 = 528208
17 + 528191 = 528208
41 + 528167 = 528208
71 + 528137 = 528208
101 + 528107 = 528208
167 + 528041 = 528208
227 + 527981 = 528208
311 + 527897 = 528208

Showing the first eight; more decompositions exist.
