Answer:
682 is the biggest number but if it is talking about the two numbers added then it is 19 and 682
Edit: If there is supposed to be a comma in-between the two pairs of numbers then the answer would be 32,665. I didn't think they could have been commas at first but if they are then 32,665 is the answer.
Explanation:
682 is bigger than all the others. 19 + 682 is bigger than all the other paired ones.
