Here's an equation that's easy to analyze with a little insight.
It's not original with me, I ran across it yesterday. (I'll provide attribution after it's solved.)
x3 - y3 = 217
Does this equation have integer solutions (pairs of {x, y} integers)? If not, prove there are none; if so, find as many as you can.
