Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528688, here are decompositions:

29 + 528659 = 528688
59 + 528629 = 528688
179 + 528509 = 528688
197 + 528491 = 528688
269 + 528419 = 528688
359 + 528329 = 528688
389 + 528299 = 528688
491 + 528197 = 528688

Showing the first eight; more decompositions exist.
