By numerically solving the Bethe-Salpeter equation, we confirm the existence of $\\Lambda_c\\bar{\\Lambda}_c$ bound states with quantum numbers $J^{PC}=0^{-+}$ and $J^{PC}=1^{--}$. We further investigate the partial decay widths of the $\\Lambda_c\\bar{\\Lambda}_c$ bound states into $N\\bar{N}$, $D\\bar{D}$, $D\\bar{D}^\\ast$, $D^\\ast\\bar{D}^\\ast$, $\\pi\\bar{\\pi}$, and $K\\bar{K}$.
