Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528708, here are decompositions:

17 + 528691 = 528708
29 + 528679 = 528708
41 + 528667 = 528708
79 + 528629 = 528708
97 + 528611 = 528708
149 + 528559 = 528708
181 + 528527 = 528708
197 + 528511 = 528708

Showing the first eight; more decompositions exist.
