Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637708, here are decompositions:

7 + 8637701 = 8637708
11 + 8637697 = 8637708
41 + 8637667 = 8637708
67 + 8637641 = 8637708
71 + 8637637 = 8637708
89 + 8637619 = 8637708
97 + 8637611 = 8637708
181 + 8637527 = 8637708

Showing the first eight; more decompositions exist.
