Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644856, here are decompositions:

13 + 8644843 = 8644856
127 + 8644729 = 8644856
223 + 8644633 = 8644856
349 + 8644507 = 8644856
379 + 8644477 = 8644856
613 + 8644243 = 8644856
643 + 8644213 = 8644856
709 + 8644147 = 8644856

Showing the first eight; more decompositions exist.
