A human was born somewhere in interval of [1;1920] A.D. They lived exactly 100 years. They lived through more years that were prime numbers than any other human (of the same lifespan) who was born in a different year from that interval of [1;1920] A.D.
Question: In what year was the human born and how many prime number years did they experience? (You can assume that the person was born in the first day of their year of birth and died on the very last day of the year of their death. Both the year of birth and the year of death can be counted as experienced if they were prime numbers.)
