Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10986, here are decompositions:

7 + 10979 = 10986
13 + 10973 = 10986
29 + 10957 = 10986
37 + 10949 = 10986
47 + 10939 = 10986
83 + 10903 = 10986
97 + 10889 = 10986
103 + 10883 = 10986

Showing the first eight; more decompositions exist.
