Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11986, here are decompositions:

5 + 11981 = 11986
17 + 11969 = 11986
47 + 11939 = 11986
53 + 11933 = 11986
59 + 11927 = 11986
83 + 11903 = 11986
89 + 11897 = 11986
173 + 11813 = 11986

Showing the first eight; more decompositions exist.
