Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616642, here are decompositions:

43 + 8616599 = 8616642
79 + 8616563 = 8616642
101 + 8616541 = 8616642
109 + 8616533 = 8616642
149 + 8616493 = 8616642
211 + 8616431 = 8616642
263 + 8616379 = 8616642
269 + 8616373 = 8616642

Showing the first eight; more decompositions exist.
