Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11892, here are decompositions:

5 + 11887 = 11892
29 + 11863 = 11892
53 + 11839 = 11892
59 + 11833 = 11892
61 + 11831 = 11892
71 + 11821 = 11892
79 + 11813 = 11892
103 + 11789 = 11892

Showing the first eight; more decompositions exist.
