    $\begingroup$ I do not think that the problem is famous for its practial applications but because it turned out to be extremely difficult to solve it. $\endgroup$ – Peter Mar 26 at 19:09

    $\begingroup$ The practical use is the huge development of modern number theory in several directions it has stimulated, even for applied areas like coding theory and cryptography. On the other hand, for practical life it has less interesting consequences. For the same question see here. $\endgroup$ – Dietrich Burde Mar 26 at 19:10

    $\begingroup$ Well, I proved it back in the eighties, but I didn't want to make it public because I hate people. $\endgroup$ – amsmath Mar 26 at 19:42
