Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528828, here are decompositions:

5 + 528823 = 528828
7 + 528821 = 528828
17 + 528811 = 528828
29 + 528799 = 528828
37 + 528791 = 528828
109 + 528719 = 528828
137 + 528691 = 528828
149 + 528679 = 528828

Showing the first eight; more decompositions exist.
