Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83988, here are decompositions:

5 + 83983 = 83988
19 + 83969 = 83988
67 + 83921 = 83988
97 + 83891 = 83988
131 + 83857 = 83988
197 + 83791 = 83988
211 + 83777 = 83988
227 + 83761 = 83988

Showing the first eight; more decompositions exist.
