Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528706, here are decompositions:

47 + 528659 = 528706
83 + 528623 = 528706
179 + 528527 = 528706
197 + 528509 = 528706
293 + 528413 = 528706
389 + 528317 = 528706
443 + 528263 = 528706
509 + 528197 = 528706

Showing the first eight; more decompositions exist.
