Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528216, here are decompositions:

19 + 528197 = 528216
53 + 528163 = 528216
79 + 528137 = 528216
89 + 528127 = 528216
109 + 528107 = 528216
163 + 528053 = 528216
173 + 528043 = 528216
223 + 527993 = 528216

Showing the first eight; more decompositions exist.
