Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83928, here are decompositions:

7 + 83921 = 83928
17 + 83911 = 83928
37 + 83891 = 83928
59 + 83869 = 83928
71 + 83857 = 83928
137 + 83791 = 83928
151 + 83777 = 83928
167 + 83761 = 83928

Showing the first eight; more decompositions exist.
