Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642744, here are decompositions:

163 + 8642581 = 8642744
211 + 8642533 = 8642744
277 + 8642467 = 8642744
463 + 8642281 = 8642744
547 + 8642197 = 8642744
571 + 8642173 = 8642744
757 + 8641987 = 8642744
787 + 8641957 = 8642744

Showing the first eight; more decompositions exist.
