Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663568, here are decompositions:

31 + 8663537 = 8663568
47 + 8663521 = 8663568
59 + 8663509 = 8663568
61 + 8663507 = 8663568
71 + 8663497 = 8663568
97 + 8663471 = 8663568
101 + 8663467 = 8663568
107 + 8663461 = 8663568

Showing the first eight; more decompositions exist.
