Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676666, here are decompositions:

7 + 8676659 = 8676666
23 + 8676643 = 8676666
79 + 8676587 = 8676666
139 + 8676527 = 8676666
149 + 8676517 = 8676666
179 + 8676487 = 8676666
199 + 8676467 = 8676666
269 + 8676397 = 8676666

Showing the first eight; more decompositions exist.
