Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646900, here are decompositions:

11 + 8646889 = 8646900
47 + 8646853 = 8646900
79 + 8646821 = 8646900
83 + 8646817 = 8646900
107 + 8646793 = 8646900
149 + 8646751 = 8646900
179 + 8646721 = 8646900
181 + 8646719 = 8646900

Showing the first eight; more decompositions exist.
