Default Prime 19 is the smallest prime...

19 (a twin) is the smallest prime such that between it and the closest square surrounding it (16) there is a prime 17.
Another example is 41...between 41 and 36 there is 37. (36 is the closest square surrounding 41, being 7^2 further away than 6^2).


89 is the first non twin prime with this property, any Others?
