Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528928, here are decompositions:

17 + 528911 = 528928
47 + 528881 = 528928
107 + 528821 = 528928
137 + 528791 = 528928
149 + 528779 = 528928
269 + 528659 = 528928
317 + 528611 = 528928
401 + 528527 = 528928

Showing the first eight; more decompositions exist.
