Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669306, here are decompositions:

13 + 8669293 = 8669306
67 + 8669239 = 8669306
73 + 8669233 = 8669306
127 + 8669179 = 8669306
193 + 8669113 = 8669306
199 + 8669107 = 8669306
223 + 8669083 = 8669306
313 + 8668993 = 8669306

Showing the first eight; more decompositions exist.
