However, Narkiewicz showed that 6 can be so represented in infinitely many ways such as and McDaniel showed that every integer has infinitely many such representations (McDaniel, 1982). Erdős conjectured that every sufficiently large integer is a sum of at most three powerful numbers; this was proved by Roger Heath-Brown (1987). More generally, we can consider the integers all of whose prime factors have exponents at least
