Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8910, here are decompositions:

17 + 8893 = 8910
23 + 8887 = 8910
43 + 8867 = 8910
47 + 8863 = 8910
61 + 8849 = 8910
71 + 8839 = 8910
73 + 8837 = 8910
79 + 8831 = 8910

Showing the first eight; more decompositions exist.
