ABSTRACT :
By grouping all the odd numbers greater than two into groups in modulo prime for all odd primes ≤ (E-3)^(1/2) (E = even number), we will get a special pattern that leads the lose of odd pairs which is not a prime pairs. With this method, we will create a base formula as an approximation to the number of prime pairs. Here, the formulation is focused on the even numbers that are critical (I refer to as the critical condition on all steps = CCAS). However, the actual initial state is in an unbalanced condition. Then, the balance and the tolerance are given in several different ways to obtain the minimum limit (lower bound) to the number of prime pairs as a guarantor formulation on the proof.
Several formula are drawn into graphics for very limited even numbers as shown on both graphs.
