On Goldbach Conjecture

The objective of the present work is to present an approach for a solution of Goldbach Conjecture. For such the method of the contradiction was adopted, breaking of the hypothesis that there is, at least, an equal number that is not the sum of two prime numbers. The premise that sustains the demonstration is the following: a prime number, which has the properties of the Theorem of Wilson, can be represented by the floor function. In applied mathematics it can be useful to know that he/she/it can assure the condition of a number as being prime number, using the floor function.
