and infinitely more can be found by simply expanding the search range, though at this point it's more efficient
(albeit more convoluted) to begin using congruences and parameterization, as stated.

Is there a pattern to the solution pairs ?
For above, it seems to be (2 N^3, 2 N^3) or (2 N^3, N^3).

What divisibility criteria did you end up using ?
