Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666598, here are decompositions:

7 + 8666591 = 8666598
79 + 8666519 = 8666598
97 + 8666501 = 8666598
107 + 8666491 = 8666598
139 + 8666459 = 8666598
167 + 8666431 = 8666598
179 + 8666419 = 8666598
181 + 8666417 = 8666598

Showing the first eight; more decompositions exist.
