Solution:

package main

func main() {
    answer := 0
    max := 0
    var solutions int
    for p := 5; p <= 1000; p++ {
        solutions = 0
        for c := p; c > p/3; c-- {
            for b := 1; b < c; b++ {
                a := p - c - b
                if isPythagoras(a, b, c) {
                    solutions++
                }
            }
        }
        if solutions > max {
            max, answer = solutions, p
        }
    }
    println(answer)
}

func isPythagoras(a, b, c int) bool {
    if a*a+b*b == c*c {
        return true
    }
    return false
}
