Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528258, here are decompositions:

11 + 528247 = 528258
41 + 528217 = 528258
61 + 528197 = 528258
67 + 528191 = 528258
127 + 528131 = 528258
131 + 528127 = 528258
151 + 528107 = 528258
167 + 528091 = 528258

Showing the first eight; more decompositions exist.
