### On the representation of an even perfect number as the sum of five cubes

Bakir Farhi

#### Abstract

The aim of this note is to show that any even perfect number, other than $6$, can be written as the sum of at most five positive integral cubes. We also conjecture that any such number can even be written as the sum of at most three positive integral cubes.
