You did not specify what should happen
a) if the third column's values are identical
b) if values can go negative
c) to lines that do not have duplicates.
Thus any proposal might need further refinement. Try:
Code:
$ awk   '{x=$1" "$2}
         $3 > Ar[x] {if (Ar[x]) print x, Ar[x] > "further"; Ar[x]=$3}
         $3 < Ar[x] {print  > "further"}
         END {for (x in Ar) print x, Ar[x]}
        ' file
