Description

Consider the divisors of 30: 1,2,3,5,6,10,15,30. It can be seen that for every divisor d of 30, d+30/d is prime.

Find the sum of all positive integers n not exceeding 100 000 000such that for every divisor d of n, d+n/d is prime.

tests:
  - text: <code>euler357()</code> should return 1739023853137.
    testString: assert.strictEqual(euler357(), 1739023853137);

function euler357() {
  // Good luck!
  return true;
}

euler357();
