ON THE WARING–GOLDBACH PROBLEM FOR CUBES
Published online by Cambridge University Press: 01 September 2009
Abstract
We prove that almost all natural numbers satisfying certain necessary congruence conditions can be written as the sum of two cubes of primes and two cubes of P2-numbers, where, as usual, we call a natural number a P2-number when it is a prime or the product of two primes. From this result we also deduce that every sufficiently large integer can be written as the sum of eight cubes of P2-numbers.
