What is the greatest 5 digit prime number?
Part of my assignement was to find the biggest 5 digit prime number with the sum of its digits = 35, since 7+7+7+7+7=35 then the range of possible numbers would be from 77777-99999, for some reson starting from 99999 seemed more safe and after a few tries I've found 99971 to be the desired number.
