Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689644, here are decompositions:

17 + 8689627 = 8689644
53 + 8689591 = 8689644
71 + 8689573 = 8689644
101 + 8689543 = 8689644
107 + 8689537 = 8689644
151 + 8689493 = 8689644
163 + 8689481 = 8689644
181 + 8689463 = 8689644

Showing the first eight; more decompositions exist.
