Erdős problem 829

Erdős Problem 829 (open). Let A⊆NA \subseteq \mathbb{N} be the set of perfect cubes. Is it true that (1A∗1A)(n)≪(log⁡n)O(1)(1_A \ast 1_A)(n) \ll (\log n)^{O(1)}? That is, does there exist a natural number CC such that the number of representations of nn as a sum of two cubes is O((log⁡n)C)O((\log n)^C) as n→∞n \to \infty?
