Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6838, here are decompositions:

5 + 6833 = 6838
11 + 6827 = 6838
47 + 6791 = 6838
59 + 6779 = 6838
101 + 6737 = 6838
137 + 6701 = 6838
149 + 6689 = 6838
179 + 6659 = 6838

Showing the first eight; more decompositions exist.
