a!localVariables(
  local!numbs: {2,7,11,15},
  local!target: 9,
  reject(
    a!isNullOrEmpty(_),
    a!forEach(
      items: local!numbs,
      expression: if(
        fv!item > local!target,
        null,
        wherecontains(local!target - fv!item, local!numbs)
      )
    )
  )
)

It works aside from Appian arrays index starting at 1. Uses only 1 forEach loop, and should be able to handle multiple correct answers. 15 lines just like the other. =/

Nice challenge. Do you have any specific question?
