Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616662, here are decompositions:

163 + 8616499 = 8616662
283 + 8616379 = 8616662
421 + 8616241 = 8616662
463 + 8616199 = 8616662
619 + 8616043 = 8616662
643 + 8616019 = 8616662
673 + 8615989 = 8616662
829 + 8615833 = 8616662

Showing the first eight; more decompositions exist.
