Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528300, here are decompositions:

11 + 528289 = 528300
37 + 528263 = 528300
53 + 528247 = 528300
83 + 528217 = 528300
103 + 528197 = 528300
109 + 528191 = 528300
137 + 528163 = 528300
163 + 528137 = 528300

Showing the first eight; more decompositions exist.
