Discovery of the Prime Number Equation(vol.3)

I found a prime number equation. (a = positive integer, t = prime number etc.) For other positive integers(a), t is an irrational number. This generates prime numbers, but also generates a composite number of prime numbers and irrational numbers. However, at this time Nevertheless, it never happens to generate all the prime numbers. About half of the prime numbers are generated. This generates prime numbers, but also generates a composite number of prime numbers and irrational numbers. It has regularity of prime number prime number. However, at this time Nevertheless, it never happens to generate all the prime numbers. About half of the prime numbers are generated. (p) is prime-number 2, 19, 33, 134, 168, 253…….are (a). Display only those whose t is an integer 49, 151, 199, 401, 449……are (t).
