Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8868, here are decompositions:

5 + 8863 = 8868
7 + 8861 = 8868
19 + 8849 = 8868
29 + 8839 = 8868
31 + 8837 = 8868
37 + 8831 = 8868
47 + 8821 = 8868
61 + 8807 = 8868

Showing the first eight; more decompositions exist.
