Project Euler #50: Consecutive prime sum

  • + 1 comment

    Forgive my ignorance, But isn't 983 the highest number below 1000 when consecutive prime numbers are added? In the problem section, they gave 953 as the highest number. Can anyone tell me how?

    sum((2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 109)) = 983

    sum((2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 241)) = 953

    Can anybody tell me the prime numbers for 953?

    Thank you
