Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659644, here are decompositions:

13 + 8659631 = 8659644
17 + 8659627 = 8659644
43 + 8659601 = 8659644
101 + 8659543 = 8659644
107 + 8659537 = 8659644
113 + 8659531 = 8659644
131 + 8659513 = 8659644
173 + 8659471 = 8659644

Showing the first eight; more decompositions exist.
