Folding only adds numbers together, so the total never changes. Both strips add up to 60. Your largest target number, 32, must be a stack of several cells added together.
Hint 2: the length budget
The strip has 11 cells and the target has 4, so the folds together must remove 7 cells. A fold removes as many cells as its shorter side has.
Hint 3: the first fold
The first fold goes between cell 10 and cell 11, counting cells from the left.

Fold 1 of 4
16886825529→16886825511
Fold between cell 10 and cell 11. The right side flips over the left side.
Fold 2 of 4
16886825511→1688682516
Fold between cell 9 and cell 10. The right side flips over the left side.
Fold 3 of 4
1688682516→16886247
Fold between cell 7 and cell 8. The right side flips over the left side.
Fold 4 of 4
16886247→1133214
Fold between cell 4 and cell 5. The right side flips over the left side.
