Split file based on file size in Korn script

I need to split a file if it is over 2GB in size (or any size), preferably split on the lines. I have figured out how to get the file size using awk, and I can split the file based on the number of lines (which I got with wc -l) but I can't figure out how to connect them together in the script.

So the command
Code:
ls -l>mylist.txt

gives me the file listing in a file, and the command
Code:
awk < mylist.txt '{if ($5>75000000) print $5 " " $NF}'

gives me a list of all the files that are larger that the size with their sizes, and the command
Code:
wc -l myfile.txt

gives me the number of lines in the file (call it 50000), and if I manually put them together, the command
Code:
split -l 25000 myfile.txt myfile.txt

gives me two files, myfile.txtaa and myfile.txtab, each with 25000 lines.

The problem is how to get them together in one script....
Thank you.
