What do you mean by "primeproduct"? Do you mean any number that has 2 as a factor?
For instance, does 2^20 = 1048576 qualify as a "primeproduct"?
If you just mean any number that has two as a factor, these are called "even numbers", and any number that ends in 0, 2, 4, 6, or 8 is such a number. Thus, here is a large even number: 7924720394820394812476
