Revision 888777 of "Euler prime" on enwiki

In [[mathematics]], '''Euler primes''' or '''Symmetric primes''' are primes that are the same distance from a given number. For example 3 and 13 are both 5 units from the number 8, Hence are symmetric primes. All [[twin prime]]s are symmetric primes.

It is [[conjecture]]d that there is at least one pair of symmetric primes for every natural number larger than 3, yet no proof has been given to date.
