Commutative Algebra, chapter VII, § 4. Modules over integrally closed Noetherian domains

Let MM be a finitely generated AA-module and let TT be its torsion submodule. Then TT is a directfactor of MM.

As M/TM/T is torsion-free and finitely generated, it is projective by Proposition 22 and the corollary therefore follows from Algebra, Chapter II, § 2, no. 2, Proposition 4.

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
