Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662566, here are decompositions:

13 + 8662553 = 8662566
79 + 8662487 = 8662566
83 + 8662483 = 8662566
113 + 8662453 = 8662566
223 + 8662343 = 8662566
229 + 8662337 = 8662566
239 + 8662327 = 8662566
293 + 8662273 = 8662566

Showing the first eight; more decompositions exist.
