Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528266, here are decompositions:

3 + 528263 = 528266
19 + 528247 = 528266
43 + 528223 = 528266
103 + 528163 = 528266
139 + 528127 = 528266
223 + 528043 = 528266
283 + 527983 = 528266
337 + 527929 = 528266

Showing the first eight; more decompositions exist.
