Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11826, here are decompositions:

5 + 11821 = 11826
13 + 11813 = 11826
19 + 11807 = 11826
37 + 11789 = 11826
43 + 11783 = 11826
47 + 11779 = 11826
83 + 11743 = 11826
107 + 11719 = 11826

Showing the first eight; more decompositions exist.
