Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528164, here are decompositions:

37 + 528127 = 528164
67 + 528097 = 528164
73 + 528091 = 528164
151 + 528013 = 528164
163 + 528001 = 528164
181 + 527983 = 528164
223 + 527941 = 528164
283 + 527881 = 528164

Showing the first eight; more decompositions exist.
