Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528286, here are decompositions:

23 + 528263 = 528286
89 + 528197 = 528286
149 + 528137 = 528286
179 + 528107 = 528286
233 + 528053 = 528286
293 + 527993 = 528286
389 + 527897 = 528286
443 + 527843 = 528286

Showing the first eight; more decompositions exist.
