Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679900, here are decompositions:

13 + 8679887 = 8679900
17 + 8679883 = 8679900
29 + 8679871 = 8679900
59 + 8679841 = 8679900
109 + 8679791 = 8679900
157 + 8679743 = 8679900
191 + 8679709 = 8679900
223 + 8679677 = 8679900

Showing the first eight; more decompositions exist.
