It takes three lines, not one, but you’re close:

result = reshape(date_num, 2, []);
result = [result; result(end,:)-1];
result = result(:)

result =

        736274
        736273
        736272
        736246
        736245
        736244
        736211
        736210
        736209
        736183
        736182
        736181
