This document discusses a method for determining if Goldbach's conjecture is true for a given even number 2n. It presents a formula (formula 3) that checks if two prime numbers p and q exist such that their sum is 2n. The formula uses sine functions and multiplications to test all possible combinations of p and q between 2 and 2n-2. An example application of the formula in a computer program finds a solution, providing evidence for Goldbach's conjecture being true for that even number. The document concludes by stating the remaining step is a formal proof that the formula always produces a valid q.
