Abstract. We make a conjecture about integer powers which states that for any integer $n\geq2$, the $n^{th}$ power of any arbitrary integer, including zero, can be expressed `primitively' and `non-trivially', in infinitely many different ways as the sum or difference of $(n + 1)$ number of other non-zero, but not necessarily distinct integral $n^{th}$ powers. The conjecture is established for squares, cubes (partly) and biquadrates, and is open for the remaining cases. Finally, a few more questions are raised for further investigation.
