Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16838, here are decompositions:

7 + 16831 = 16838
79 + 16759 = 16838
97 + 16741 = 16838
109 + 16729 = 16838
139 + 16699 = 16838
181 + 16657 = 16838
271 + 16567 = 16838
277 + 16561 = 16838

Showing the first eight; more decompositions exist.
