We calculate the decay rate B-> X_s photon photon via intermediate psuedoscalar charmonium eta_c. This process is thought to be the main long-distance contribution which dominates the corresponding inclusive rare B decay. We point out that once the momentum dependence of eta_c-> photon photon conversion strength, due to off-shellness of the intermediate eta_c, is taken into account, the rate of this decay mode is reduced. The change in differential decay rate in region of spectrum immediately below m_{eta_c} is more significant. On the other hand, we point out that the unexpectedly large branching ratio for B-> X_s eta' which is recently observed by CLEO could indicate a potentially larger long-distance contribution via eta' resonance.
