Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528222, here are decompositions:

5 + 528217 = 528222
31 + 528191 = 528222
59 + 528163 = 528222
131 + 528091 = 528222
179 + 528043 = 528222
181 + 528041 = 528222
229 + 527993 = 528222
239 + 527983 = 528222

Showing the first eight; more decompositions exist.
