Indeed.  Great fun.  It also caused me to remember a few stories about
finding the smallest number that's the sum of two cubes in two
different ways.  It was given in a class I took as an undergraduate, and,
of course, it is a famous piece of lore.  Ramamujan asked Hardy the number
of the taxicab he took when he visited Ramamujan in the hospital.  Hardy
said 1729, an uninteresting number.  "On the contrary," responded
Ramamujan.  See https://en.wikipedia.org/wiki/1729_(number)

When I was at MIT, Bill Henneman, a self taught awesome mathematician, said
he participated in a programming contest where they were presented with
that exact problem.  They were allowed to choose any programming language.
The fastest program determined the winner.  Henneman chose LISP and
submitted "(Print 1729)"
