Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83900, here are decompositions:

31 + 83869 = 83900
43 + 83857 = 83900
67 + 83833 = 83900
109 + 83791 = 83900
127 + 83773 = 83900
139 + 83761 = 83900
163 + 83737 = 83900
181 + 83719 = 83900

Showing the first eight; more decompositions exist.
