Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83838, here are decompositions:

5 + 83833 = 83838
47 + 83791 = 83838
61 + 83777 = 83838
101 + 83737 = 83838
137 + 83701 = 83838
149 + 83689 = 83838
197 + 83641 = 83838
199 + 83639 = 83838

Showing the first eight; more decompositions exist.
