We first classify all integers ≥2 into eight kinds, and that formulate each of seven kinds therein into a sum of three unit fractions. For remainder one kind, we classify it into three genera, and that formulate each of two genera therein into a sum of three unit fractions. For remainder one genus, we classify it into five sorts, and that formulate each of three sorts therein into a sum of three unit fractions. For remainder two sorts i.e. 4/(49+120c) and 4/(121+120c) with c≥0, we prove them by logical inference. But miss out 3587 concrete fractions to await computer programming to solve the problem that express each of them into a sum of three unit fractions.
