Deconcentrate is formed from "de-" (meaning down or away) and "concentrate" (from Latin "concentrare", meaning to bring together). The word means to move away from a state of concentration or to disperse.
Think of 'moving away' ('de-') from a state of 'bringing together' ('concentrate') — that's why deconcentrate means to disperse or reduce focus.
