    8 (about Goldbachs conjecture) is one that I don’t quite get. Isn’t the number 8 already proof that this isn’t true (sum of 4+4)?

      8 is the sum of 5+3 both of which are primes. I think the Conjecture just states that there is a sum of two primes not every sum consists only of primes

        Ah gotcha! I thought it meant exclusively prime numbers

          Then wouldn’t 4 fail the conjecture? 4 = 1+ 3 but 1 is not a prime.

          Nevermind my sleepy self somehow thought 2 isn’t a prime number :)
