Euler prime
In [[number theory]], '''Euler primes''' or '''symmetric primes''' are [[prime number|prime]]s that are the same distance from a given integer. {{fact}} For example 3 and 13 are both 5 units from the number 8, hence are symmetric primes. All [[twin prime]]s, [[cousin prime]]s, and [[sexy prime]]s are symmetric primes.

Euler/symmetric primes constitute a ''Goldbach partition'', which is defined as a pair of primes ''p'',''q'' that sum to an even integer. It would appear that all three terms are synonymous, the latter one seemingly most used in the literature.
