So whenever a new Mersenne prime is found we get a new even perfect number for free.

Also, using this formula is working correct. On condition that ‘p’ is prime number, we can find first 4 of them; p = 2: 2^1(2^2−1) = 6 p = 3: 2^2(2^3−1) = 28 p = 5: 2^4(2^5−1) = 496 p = 7: 2^6(2^7−1) = 8128pic.twitter.com/n3aO9izj10

It's interesting to say that up to this day, there are only 4 perfect numbers discovered.
