Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662664, here are decompositions:

7 + 8662657 = 8662664
67 + 8662597 = 8662664
181 + 8662483 = 8662664
193 + 8662471 = 8662664
211 + 8662453 = 8662664
223 + 8662441 = 8662664
337 + 8662327 = 8662664
421 + 8662243 = 8662664

Showing the first eight; more decompositions exist.
