This is apparently the smallest solution.
The derivation of the solution itself requires an understanding of Diophantine equations and elliptical curves, which I will not pretend to understand well enough to summarize.

From the same article, this is a solution when negative integers are allowed:
{{x -> 11, y -> 9, z -> -5}}
