Is the difference between two even numbers positive?

The difference between the two even numbers may or may not be positive. Suppose I even number is 2m and the second number is 2n where 2m is greater than 2n . 2n - 2m is a negative number while 2m - 2n is a positive number . read more

If a number is the average (or difference) of two primes, by doubling the number it has a partition of those two primes. So, for example, [math](7+31)/2 = 19[/math] becomes [math]7+31 = 2*19[/math]. The Goldbach conjecture applies to even numbers only, but the average of two primes applies to every number - even, odd, prime - bigger than 3. read more
