We present an exploration of the unpolarized isovector proton generalized parton distributions (GPDs) Hu−d(x,ξ,t) and Eu−d(x,ξ,t) in the pseudo-distribution formalism using distillation. Taking advantage of the large kinematic coverage made possible by this approach, we present results on the moments of GPDs up to the order x3 -- including their skewness dependence -- at a pion mass mπ=358 MeV and a lattice spacing a=0.094 fm.
