Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655668, here are decompositions:

19 + 8655649 = 8655668
31 + 8655637 = 8655668
37 + 8655631 = 8655668
211 + 8655457 = 8655668
337 + 8655331 = 8655668
409 + 8655259 = 8655668
457 + 8655211 = 8655668
631 + 8655037 = 8655668

Showing the first eight; more decompositions exist.
