Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666888, here are decompositions:

7 + 8666881 = 8666888
79 + 8666809 = 8666888
397 + 8666491 = 8666888
409 + 8666479 = 8666888
457 + 8666431 = 8666888
541 + 8666347 = 8666888
619 + 8666269 = 8666888
751 + 8666137 = 8666888

Showing the first eight; more decompositions exist.
