Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637656, here are decompositions:

19 + 8637637 = 8637656
37 + 8637619 = 8637656
163 + 8637493 = 8637656
229 + 8637427 = 8637656
277 + 8637379 = 8637656
283 + 8637373 = 8637656
337 + 8637319 = 8637656
367 + 8637289 = 8637656

Showing the first eight; more decompositions exist.
