Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708816, here are decompositions:

13 + 8708803 = 8708816
199 + 8708617 = 8708816
307 + 8708509 = 8708816
367 + 8708449 = 8708816
547 + 8708269 = 8708816
619 + 8708197 = 8708816
643 + 8708173 = 8708816
673 + 8708143 = 8708816

Showing the first eight; more decompositions exist.
