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 m_π = 358 MeV and a lattice spacing a = 0.094 fm.
