Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528766, here are decompositions:

3 + 528763 = 528766
47 + 528719 = 528766
59 + 528707 = 528766
107 + 528659 = 528766
137 + 528629 = 528766
239 + 528527 = 528766
257 + 528509 = 528766
347 + 528419 = 528766

Showing the first eight; more decompositions exist.
