Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528220, here are decompositions:

3 + 528217 = 528220
23 + 528197 = 528220
29 + 528191 = 528220
53 + 528167 = 528220
83 + 528137 = 528220
89 + 528131 = 528220
113 + 528107 = 528220
167 + 528053 = 528220

Showing the first eight; more decompositions exist.
