👉 In mathematics, a semivisible number is defined as one that can be expressed as the sum of two or more prime numbers. This means that if you have a number n, it can be written in the form of p + q where p and q are both primes. For example, 17 is a semivisible number because it can be expressed as 2 + 5 = 7. Another example is 30, which can be expressed as 5 + 2
