According to the Pythagorean conception, how are even and odd numbers defined?

Par is the number that can be divided into two equal parts without a unit in the middle, and odd is the one that cannot be divided into two equal parts because there is always a unit in the middle.
Another characterization shows us the concern with the nature of numbers: a number is even if it can be divided into two equal or unequal parts, but in none of these divisions is there a mixture of even nature with odd nature, nor of odd with even. This has only one exception, which is the principle of the pair, the number 2, which does not admit division into unequal parts because it is formed by two units and, if this can be said, by the first even number, 2.
