Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528268, here are decompositions:

5 + 528263 = 528268
71 + 528197 = 528268
101 + 528167 = 528268
131 + 528137 = 528268
137 + 528131 = 528268
227 + 528041 = 528268
281 + 527987 = 528268
347 + 527921 = 528268

Showing the first eight; more decompositions exist.
