Hi,
Is this statement true or false:
There is only one number n for which:
n is the only number that has exactly three primes where for each of the three primes p(x), n - p(x) equals n + p(x) and additionally all n - p(x) are equal to prime numbers.
I've verified this as true for all numbers up to 8167 so far.
n=18 by the way
cheers, Jamie
