Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669684, here are decompositions:

13 + 8669671 = 8669684
61 + 8669623 = 8669684
73 + 8669611 = 8669684
157 + 8669527 = 8669684
241 + 8669443 = 8669684
367 + 8669317 = 8669684
433 + 8669251 = 8669684
571 + 8669113 = 8669684

Showing the first eight; more decompositions exist.
