loop that will output in order from 1 to 5 []bytes in golang

Question

How to make a loop that will output in order from 1 to 5 []bytes?

Here is what I need in the output:

[0]
[1]
[2]
...
[255]
[0 1]
[1 1]
[2 1]
...
etc (to max 5 bytes)

For example, if I doing a normal loop from numbers and turn them into bytes using these functions:

for i := 0; i < 8589934590; i++ {
    b : intToBytes(i)
    fmt.Println(b)
}

func intToBytes(val int) []byte {
    r := make([]byte, 5)
    for i := int(0); i < 5; i++ {
        r[i] = byte((val >> (8 * i)) & 0xff)
    }
    return r
}

there will be extra zeros at the end of the output.

If this option is correct, then how to get rid of extra zeros?
