:How about using Goldbach conjectue ( tested true > 1e18 ).All numbers are a sum of max three primes<BR>
proper div sum(p*q) = 1+p+q / p<
proper div sum(p*q*r) = 1+p+q+r+p*q+p*r+q*r/ p<
: is limit for checks == limit^(1/3) or limit/3
:<b>EDIT found earlier failure at 300,000</b> used special glasses ;-)
