Well an upper push would be bench press, and an upper pull would be rows. A lower push would be squats, and a lower pull would be deadlifts.
If you separate movements like that you would have a 4 day upper/lower split with no effort at all.
Upper Push Day - Bench, Military Press, Dips
Upper Pull Day - Rows, Pullups.
Lower Push Day - Squats, Lunges, Leg Press
Lower Pull Day - Deadlifts, Good Mornings, SHELC
Then you can move on to the important stuff like training variables (volume, intensity, etc) and periodization (how you will progress towards your goal throughout the program). Thats where the action happens, not in the split or exercise selection, so honestly the split doesn't matter too much so long as it's balanced and comprehensive.
