Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669120, here are decompositions:

3 + 8669117 = 8669120
7 + 8669113 = 8669120
13 + 8669107 = 8669120
37 + 8669083 = 8669120
79 + 8669041 = 8669120
127 + 8668993 = 8669120
223 + 8668897 = 8669120
283 + 8668837 = 8669120

Showing the first eight; more decompositions exist.
