Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528148, here are decompositions:

11 + 528137 = 528148
17 + 528131 = 528148
41 + 528107 = 528148
107 + 528041 = 528148
167 + 527981 = 528148
227 + 527921 = 528148
239 + 527909 = 528148
251 + 527897 = 528148

Showing the first eight; more decompositions exist.
