Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663648, here are decompositions:

127 + 8663521 = 8663648
139 + 8663509 = 8663648
151 + 8663497 = 8663648
181 + 8663467 = 8663648
211 + 8663437 = 8663648
337 + 8663311 = 8663648
439 + 8663209 = 8663648
547 + 8663101 = 8663648

Showing the first eight; more decompositions exist.
