Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528816, here are decompositions:

5 + 528811 = 528816
17 + 528799 = 528816
37 + 528779 = 528816
53 + 528763 = 528816
97 + 528719 = 528816
107 + 528709 = 528816
109 + 528707 = 528816
137 + 528679 = 528816

Showing the first eight; more decompositions exist.
