Take a prime natural N
Subtract a prime natural X, where X < N
If N-X < X then add N to the difference and subtract X.
If you do this for N steps, you'll end up at 0.
I'm a brainlet and I don't understand this. I know it's because of modular arithmetic, but why does it always seem to come up to N steps with primes?
