Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23838, here are decompositions:

5 + 23833 = 23838
7 + 23831 = 23838
11 + 23827 = 23838
19 + 23819 = 23838
37 + 23801 = 23838
71 + 23767 = 23838
97 + 23741 = 23838
149 + 23689 = 23838

Showing the first eight; more decompositions exist.
