Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608644, here are decompositions:

17 + 8608627 = 8608644
41 + 8608603 = 8608644
47 + 8608597 = 8608644
53 + 8608591 = 8608644
61 + 8608583 = 8608644
71 + 8608573 = 8608644
73 + 8608571 = 8608644
101 + 8608543 = 8608644

Showing the first eight; more decompositions exist.
