See Example for string to big int conversion.

package main


import (
    "fmt"
    "log"
    "math/big"
)

func main() {
    i := new(big.Int)
    _, err := fmt.Sscan("18446744073709551617", i)
    if err != nil {
        log.Println("error scanning value:", err)
    } else {
        fmt.Println(i)
    }
}

Output:

18446744073709551617
