Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11838, here are decompositions:

5 + 11833 = 11838
7 + 11831 = 11838
11 + 11827 = 11838
17 + 11821 = 11838
31 + 11807 = 11838
37 + 11801 = 11838
59 + 11779 = 11838
61 + 11777 = 11838

Showing the first eight; more decompositions exist.
