how many?

Extract from unit 1 of BT6101 (Theravada): "The Dighanikāya contains 34 suttantas, the Majjhimanikāya 152; the Samyuttanikāya, according to tradition, 7762, and the Anguttaranikāya 9557."

Numbers from p. 72 of Hirakawa's "History of Indian Buddhism": DN 34, MN 152, SN 2872 (!), AN 2198 (!).

2872 is clearer much smaller than 7762, and so is 2198 compared to 9557...
so which numbers should we consider?
