Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663644, here are decompositions:

23 + 8663621 = 8663644
107 + 8663537 = 8663644
137 + 8663507 = 8663644
173 + 8663471 = 8663644
383 + 8663261 = 8663644
491 + 8663153 = 8663644
641 + 8663003 = 8663644
653 + 8662991 = 8663644

Showing the first eight; more decompositions exist.
