Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528224, here are decompositions:

7 + 528217 = 528224
61 + 528163 = 528224
97 + 528127 = 528224
127 + 528097 = 528224
181 + 528043 = 528224
211 + 528013 = 528224
223 + 528001 = 528224
241 + 527983 = 528224

Showing the first eight; more decompositions exist.
