Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528468, here are decompositions:

67 + 528401 = 528468
139 + 528329 = 528468
151 + 528317 = 528468
179 + 528289 = 528468
251 + 528217 = 528468
271 + 528197 = 528468
277 + 528191 = 528468
331 + 528137 = 528468

Showing the first eight; more decompositions exist.
