Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699666, here are decompositions:

7 + 8699659 = 8699666
109 + 8699557 = 8699666
127 + 8699539 = 8699666
223 + 8699443 = 8699666
277 + 8699389 = 8699666
373 + 8699293 = 8699666
397 + 8699269 = 8699666
433 + 8699233 = 8699666

Showing the first eight; more decompositions exist.
