Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11904, here are decompositions:

7 + 11897 = 11904
17 + 11887 = 11904
37 + 11867 = 11904
41 + 11863 = 11904
71 + 11833 = 11904
73 + 11831 = 11904
83 + 11821 = 11904
97 + 11807 = 11904

Showing the first eight; more decompositions exist.
