Sorting large data set

I am trying to sort a large set of data, approximately 1.4 million pairs. The data is currently all on 1 worksheet in columns next to each other. I need to sort them by the weight column so that the lightest is the top left pair and the heaviest is the bottom right. I attached a small subset of the data sorted and unsorted to hopefully explain what I need better than I can in words. Columns A and B, C and D E and F and G and H are paired. In the actual data set the data continues for all 65536 rows and to column AY.

Thanks for any help you can give
