I once had a surprising moment when I plotted the graph of (p + q) vs. pq for primes p and q and observed the points forming streaks of dots. While surprising at first, it could be explained trivially with a little bit of analysis. I have saved the graph here: https://github.com/mycask/rsa-graph Spoiler Alert: The section named 'Streaks' right after the graph plot has spoilers.
