Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669340, here are decompositions:

7 + 8669333 = 8669340
11 + 8669329 = 8669340
23 + 8669317 = 8669340
47 + 8669293 = 8669340
61 + 8669279 = 8669340
89 + 8669251 = 8669340
101 + 8669239 = 8669340
103 + 8669237 = 8669340

Showing the first eight; more decompositions exist.
