Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9918, here are decompositions:

11 + 9907 = 9918
17 + 9901 = 9918
31 + 9887 = 9918
47 + 9871 = 9918
59 + 9859 = 9918
61 + 9857 = 9918
67 + 9851 = 9918
79 + 9839 = 9918

Showing the first eight; more decompositions exist.
