If we go with the flow and exclude 1 (so we don't have to rewrite all our theorems) and assume that all even numbers greater than 2 can be represented as a sum of two prime factors we have a problem... How does one sum 4? 2 + 2? We certainly can't use 3 + 1. If we allow repetition *and* the number 2 as a prime then all even numbers can be written as a string of 2's summed appropriately. ____________________________________________________________________ Lawyers ask the wrong questions when they don't want the right answers.
