Lay salmon slices flat. Spread each slice thickly with 2 tablespoons cream cheese. Roll up jelly roll-style into even, 1-inch thick rolls. Wrap each tightly in plastic wrap, twisting ends to make a compact package. Refrigerate for at least 1 hour to firm. Using a sharp knife, cut each into 1/4-inch thick rounds. Place one round on each cucumber.
