    Another: {(197837, 738791), (705247, 742507), (764969, 969467)} also gives 24/48 primes.  If there isn't one producing 25, then I'll not report on this again

Group Description

PrimeNumbers is a e-mail discussion list for those
who enjoy prime numbers.  Some look for patterns,
some seek to find new records, others try to understand
the distribution.  We try to limit our discussion to
prime numbers, primality testing, and very closely
related subjects.

If you enjoy prime numbers there are similar lists you
might enjoy, such as PrimeForm
focusing on primality proving programs and
GIMPS'
Mersenne
Primes list. 

If you think you have a Goldbach proof, then please note that there are groups which deal specifically with such matters, perhaps try those first?
