The analysis introduces a means by which key odd moments can be obtained from the even moments in circumstances where only the latter are available. Combining these elements, one arrives at parameter-free lQCD-based predictions for the pointwise behaviour of pion valence, glue, and sea DFs, with sound uncertainty estimates. The behaviour of the pion DFs at large light-front momentum fraction, <math><mi>x</mi><mo>\u2273</mo><mn>0.85</mn></math>, is found to be consistent with QCD expectations and continuum analyses of pion structure functions, i.e., damping like <math><msup><mrow><mo>(</mo><mn>1</mn><mo>\u2212</mo><mi>x</mi><mo>)</mo></mrow><mrow><msub><mrow><mi>\u03b2</mi></mrow><mrow><mi>parton</mi></mrow></msub></mrow></msup></math>, with <math><msub><mrow><mi>\u03b2</mi></mrow><mrow><mi>valence</mi></mrow></msub><mo>\u2248</mo><mn>2.4</mn></math>, <math><msub><mrow><mi>\u03b2</mi></mrow><mrow><mi>glue</mi></mrow></msub><mo>\u2248</mo><mn>3.6</mn></math>, <math><msub><mrow><mi>\u03b2</mi></mrow><mrow><mi>sea</mi></mrow></msub><mo>\u2248</mo><mn>4.6</mn></math>. It may be possible to test these predictions using data from forthcoming experiments."
