Is there any way to get two factors of a number whose sum of the squares is a perfect square. As an example
$19354423920$ is a number. which has $4262$, $4541160$ as factors ($19354423920 = 4262 * 4541160$).
The sum of the squares of the factors will then be a perfect square like this $4262^2 + 4541160^2 = 4541162^2$.
How does one find out this kind of factors from a number?
