(edit: clarification: Robert also solved the "positive part", but charybdis' proof is simpler and constructive, however, charybdis, (as the others too), doesn't solve the negative part, i.e. "powers of two can't be written as so", (s)he only shows that powers of two can't be written as so by his/her method, which is no warranty that somebody else won't come with a new method that allows a particular power of two to be written as so).
