First, well done. An if you aren't larping us, might be time to pick up on that 'disclosure' thread. Think of how software vulnerabilities are handled today as an example of how this might play out.
Actually, don't give the other, it's an RSA. Wouldn't want you getting into trouble now CA.
Give us this one, it's a c that is the product of two primes a and b. You won't be 'breaking' anything, but this one example. Can give you dozens of examples like this.

It's 180 digits long, easier than RSA100 even.
Godspeed, you've got 30 minutes, starting … NOW.
