Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637816, here are decompositions:

29 + 8637787 = 8637816
37 + 8637779 = 8637816
67 + 8637749 = 8637816
149 + 8637667 = 8637816
179 + 8637637 = 8637816
197 + 8637619 = 8637816
199 + 8637617 = 8637816
293 + 8637523 = 8637816

Showing the first eight; more decompositions exist.
