According to 1 Kings 7:20, there were 200 pomegranates cast in two rows around the capitals of the bronze pillars of the Temple. According to Jeremiah 52:23, four pomegranates in each row were set aside from the rest. I imagine that there were 96 of one size in each of the two rows with four larger pomegranates on opposite sides of the column, perhaps representing the four corners of the earth.
Bronze represents judgment, while four represents life and the world, and two sets of 200 may represent an appeal for mercy. Consider that Jacob sent 200 female goats and 200 ewes to Esau, Abigail gave 200 loaves and 200 fig cakes to David, and Ziba gave 200 loaves and 200 fruits to David.
