Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528672, here are decompositions:

5 + 528667 = 528672
13 + 528659 = 528672
41 + 528631 = 528672
43 + 528629 = 528672
61 + 528611 = 528672
113 + 528559 = 528672
163 + 528509 = 528672
181 + 528491 = 528672

Showing the first eight; more decompositions exist.
