Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528888, here are decompositions:

5 + 528883 = 528888
7 + 528881 = 528888
11 + 528877 = 528888
67 + 528821 = 528888
89 + 528799 = 528888
97 + 528791 = 528888
109 + 528779 = 528888
179 + 528709 = 528888

Showing the first eight; more decompositions exist.
