Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685644, here are decompositions:

7 + 8685637 = 8685644
13 + 8685631 = 8685644
43 + 8685601 = 8685644
61 + 8685583 = 8685644
67 + 8685577 = 8685644
73 + 8685571 = 8685644
127 + 8685517 = 8685644
151 + 8685493 = 8685644

Showing the first eight; more decompositions exist.
