Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669000, here are decompositions:

7 + 8668993 = 8669000
103 + 8668897 = 8669000
127 + 8668873 = 8669000
163 + 8668837 = 8669000
199 + 8668801 = 8669000
313 + 8668687 = 8669000
499 + 8668501 = 8669000
541 + 8668459 = 8669000

Showing the first eight; more decompositions exist.
