Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11988, here are decompositions:

7 + 11981 = 11988
17 + 11971 = 11988
19 + 11969 = 11988
29 + 11959 = 11988
47 + 11941 = 11988
61 + 11927 = 11988
79 + 11909 = 11988
101 + 11887 = 11988

Showing the first eight; more decompositions exist.
