Relativity theory must be used. Then,it is neither mass alone or energy alone that is conserved, but "mass-energy" is conserved, where mass and energy are considered as "equivalent" properties. Therefore, during positive beta decay, total mass increases, but energy decreases. This is how the reaction is feasible.
