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)?

1 is not a prime number. It would have to be 3+5

~~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 :)
