Represent a vector as ± form

I have a vector

v1 = [86 90 87 89 88];

I want to represent the vector v1 as 88±2

Please please me to represent any vector of any size as ± form?

Another example

v2 = [0.8331;0.8771;0.8531;0.8558;0.8649];

v1 = [86 90 87 89 88];
iwant = [v1-2;v1+2]  % first row is v1+2 and second row is v1-2 

iwant = 2×5

84 88 85 87 86 88 92 89 91 90

No Sir, I dont want to get the answer, I want the value 88 and the value after ± symbol

I want to get 88 and 2, in the first case, and in the second case I need to find the two values, before the ± symbol and after the ± symbol

Taking this as a demo, second one you have to do it yourself.
