Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9986, here are decompositions:

13 + 9973 = 9986
19 + 9967 = 9986
37 + 9949 = 9986
79 + 9907 = 9986
103 + 9883 = 9986
127 + 9859 = 9986
157 + 9829 = 9986
199 + 9787 = 9986

Showing the first eight; more decompositions exist.
