Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528424, here are decompositions:

5 + 528419 = 528424
11 + 528413 = 528424
23 + 528401 = 528424
41 + 528383 = 528424
107 + 528317 = 528424
227 + 528197 = 528424
233 + 528191 = 528424
257 + 528167 = 528424

Showing the first eight; more decompositions exist.
