Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669220, here are decompositions:

13 + 8669207 = 8669220
31 + 8669189 = 8669220
41 + 8669179 = 8669220
61 + 8669159 = 8669220
97 + 8669123 = 8669220
103 + 8669117 = 8669220
107 + 8669113 = 8669220
113 + 8669107 = 8669220

Showing the first eight; more decompositions exist.
