We exhibit a new symmetry of the integrand of the correlation function of four stress-tensor multiplets in N=4 SYM. It allows us to predict the integrand up to six loops, without computing Feynman diagrams. We use these results to derive the anomalous dimension of the Konishi operator up to five loops, confirming the predictions of the thermodynamic Bethe Ansatz. We also discuss the relationship between correlation functions and scattering amplitudes.
