We consider nonplanar contributions to the correlation functions of Berenstein-Maldacena-Nastase (BMN) operators in free N = 4 super Yang-Mills theory. We recalculate these nonplanar contributions from a different kind of diagram and find some exact agreement. The vertices of these diagrams are represented by free planar three-point functions; thus, our calculations provide some interesting identities for correlation functions of BMN operators in N = 4 super Yang-Mills theory. These diagrams look very much like loop diagrams in a second quantized string field theory; thus these identities could possibly be interpreted as natural consequences of the pp-wave/conformal field theory correspondence. For convenience we will call these diagrams ``string theory diagram,'' although there are reasonable doubts as to whether these calculations are truly string theory calculations since it is not known how to compute general loop amplitudes in a second quantized string theory.
