Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83864, here are decompositions:

7 + 83857 = 83864
31 + 83833 = 83864
73 + 83791 = 83864
103 + 83761 = 83864
127 + 83737 = 83864
163 + 83701 = 83864
211 + 83653 = 83864
223 + 83641 = 83864

Showing the first eight; more decompositions exist.
