Calmo numbers

Definition Let n be a natural number. Let the real divisors of n be: d(1),d(2),d(3),...,d(k), where k is divisible by 3. Add the first three divisors, then the next three, and so on. If the partial sums are prime numbers, then n is called a Calmo number. Example n = 165 divisors = [3 5 11 15 33 55] 3 + 5 + 11 = 19 is prime number 15 + 33 + 55 = 103 is prime number Task let's find Calmo numbers under 1000.
