Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698666, here are decompositions:

23 + 8698643 = 8698666
107 + 8698559 = 8698666
113 + 8698553 = 8698666
149 + 8698517 = 8698666
167 + 8698499 = 8698666
173 + 8698493 = 8698666
269 + 8698397 = 8698666
443 + 8698223 = 8698666

Showing the first eight; more decompositions exist.
