The purpose of pair programming and the purpose of code review are not quite the same. Pair programming is a high-context activity where two programmers collaborate closely on building something. Code review is a tool to simulate looking at code that you haven't just worked on with high-context, and seeks to assess whether it is understandable to someone in that position. Since code is read far more often than it is written, code review can be a very effective tool for maintaining the long-term health of a code-base when applied in this way.
