Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11976, here are decompositions:

5 + 11971 = 11976
7 + 11969 = 11976
17 + 11959 = 11976
23 + 11953 = 11976
37 + 11939 = 11976
43 + 11933 = 11976
53 + 11923 = 11976
67 + 11909 = 11976

Showing the first eight; more decompositions exist.
