Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528288, here are decompositions:

41 + 528247 = 528288
71 + 528217 = 528288
97 + 528191 = 528288
151 + 528137 = 528288
157 + 528131 = 528288
181 + 528107 = 528288
191 + 528097 = 528288
197 + 528091 = 528288

Showing the first eight; more decompositions exist.
