Commutative Algebra, chapter IV, § 2. Primary decomposition

In a principal ideal domain AA, the primary ideals are (0)(0) and the ideals of the form ApnAp^n, where pp is an extremal element and n≥1n \geq 1; this follows immediately from Example 3.

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