Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676638, here are decompositions:

7 + 8676631 = 8676638
37 + 8676601 = 8676638
97 + 8676541 = 8676638
151 + 8676487 = 8676638
241 + 8676397 = 8676638
277 + 8676361 = 8676638
337 + 8676301 = 8676638
409 + 8676229 = 8676638

Showing the first eight; more decompositions exist.
