Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669900, here are decompositions:

3 + 8669897 = 8669900
7 + 8669893 = 8669900
79 + 8669821 = 8669900
199 + 8669701 = 8669900
229 + 8669671 = 8669900
271 + 8669629 = 8669900
277 + 8669623 = 8669900
307 + 8669593 = 8669900

Showing the first eight; more decompositions exist.
