We have calculated the E1 and E2 contributions to the low-energy $^{8}\mathrm{B}$${+}^{208}$Pb\ensuremath{\rightarrow}p${+}^{7}$Be${+}^{208}$Pb Coulomb dissociation cross sections using the kinematics of a recent experiment at RIKEN. Using a potential model description of the $^{7}\mathrm{Be}$(p,\ensuremath{\gamma}${)}^{8}$B reaction, we find that the E2 contributions cannot a priori be ignored in the analysis of the data. Its inclusion reduces the extracted $^{7}\mathrm{Be}$(p,\ensuremath{\gamma}${)}^{8}$B S factor at solar energies by about 25%.
