How many years have passed since the formation of the ancient Egyptian state until the fall of Assyria?

Ancient Egypt arose at the turn of 4-3 thousand BC, and its unification into a single state took place in 3050 BC. The Assyrian Empire fell into decay in 605 BC. Based on these data, we can say that the difference between these events is 2445 years. So in the 7th century, one of the most powerful empires of the east was destroyed, which kept many peoples of Mesopotamia in fear and obedience.
