Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637726, here are decompositions:

29 + 8637697 = 8637726
59 + 8637667 = 8637726
89 + 8637637 = 8637726
107 + 8637619 = 8637726
109 + 8637617 = 8637726
199 + 8637527 = 8637726
233 + 8637493 = 8637726
277 + 8637449 = 8637726

Showing the first eight; more decompositions exist.
