Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668648, here are decompositions:

5 + 8668643 = 8668648
11 + 8668637 = 8668648
71 + 8668577 = 8668648
101 + 8668547 = 8668648
227 + 8668421 = 8668648
269 + 8668379 = 8668648
281 + 8668367 = 8668648
347 + 8668301 = 8668648

Showing the first eight; more decompositions exist.
