Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528628, here are decompositions:

5 + 528623 = 528628
17 + 528611 = 528628
101 + 528527 = 528628
137 + 528491 = 528628
227 + 528401 = 528628
311 + 528317 = 528628
431 + 528197 = 528628
461 + 528167 = 528628

Showing the first eight; more decompositions exist.
