Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528400, here are decompositions:

17 + 528383 = 528400
71 + 528329 = 528400
83 + 528317 = 528400
101 + 528299 = 528400
137 + 528263 = 528400
233 + 528167 = 528400
263 + 528137 = 528400
269 + 528131 = 528400

Showing the first eight; more decompositions exist.
