Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669928, here are decompositions:

5 + 8669923 = 8669928
17 + 8669911 = 8669928
31 + 8669897 = 8669928
67 + 8669861 = 8669928
97 + 8669831 = 8669928
107 + 8669821 = 8669928
151 + 8669777 = 8669928
227 + 8669701 = 8669928

Showing the first eight; more decompositions exist.
