2 is 4-2*Originally posted by Gastel***Is there a pattern for prime numbers that are the next perfect square minus a prime?**

1 is not (as it is not a prime although 4-3 would be what I was talking about)

2 is 4-2

7 is 9-2

23 is 25-2

47 is 49-2

79 is 81-2

Does this pattern continue forever? Can it be proven?

7 is 9-2

11 is 16-5

5 is 16-11

23 is 25-2

19 is 36-17

17 is 36-19

47 is 49-2

41 is 64-23

23 is 64-41

79 is 81-2

You skipped a few squares.
