Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669994, here are decompositions:

5 + 8669989 = 8669994
13 + 8669981 = 8669994
31 + 8669963 = 8669994
71 + 8669923 = 8669994
83 + 8669911 = 8669994
97 + 8669897 = 8669994
101 + 8669893 = 8669994
163 + 8669831 = 8669994

Showing the first eight; more decompositions exist.
