I think that any of the proposed solutions can be adapted
to avoid boxing.

For example:
   pair3nb=: [:-.&0 0[:,/({.,.}.)[EMAIL PROTECTED]

That said, given the nature of the problem, I am not
sure that this is a useful change.

I think you meant
   ({~ (</ #&(,/) ,"0/)[EMAIL PROTECTED]@#) 40 10 20 31 21 32 3
