The X(3872) with quantum numbers J{sup PC}=1{sup ++} is considered as a composite hadronic state comprised of the dominant molecular D{sup 0}D*{sup 0} component and other hadronic pairs--D{sup {+-}}D*{sup {+-}}, J/{psi}{omega}, and J/{psi}{rho}. Applying the compositeness condition we constrain the couplings of the X(3872) to its constituents. We calculate two- and three-body hadronic decays of the X(3872) to charmonium states {chi}{sub cJ} and pions using a phenomenological Lagrangian approach. Next using the estimated XJ/{psi}{omega} and XJ/{psi}{rho} couplings we calculate the widths of X(3872){yields}J/{psi}+h transitions, where h={pi}{sup +}{pi}{sup -}, {pi}{sup +}{pi}{sup -}{pi}{sup 0}, {pi}{sup 0}{gamma}, and {gamma}. The obtained results for the decay pattern of the X(3872) in a molecular interpretation could be useful for running and planned experiments.
