Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11930, here are decompositions:

3 + 11927 = 11930
7 + 11923 = 11930
43 + 11887 = 11930
67 + 11863 = 11930
97 + 11833 = 11930
103 + 11827 = 11930
109 + 11821 = 11930
151 + 11779 = 11930

Showing the first eight; more decompositions exist.
