Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8866, here are decompositions:

3 + 8863 = 8866
5 + 8861 = 8866
17 + 8849 = 8866
29 + 8837 = 8866
47 + 8819 = 8866
59 + 8807 = 8866
83 + 8783 = 8866
113 + 8753 = 8866

Showing the first eight; more decompositions exist.
