When you split pension, the transferor (the person who is giving a portion of the pension to the spouse) will have this as a deduction at line 210 (so total income will not be affected, but net income will show the deduction). The person who receives the pension, will have this amount on line 116 (so his/her total income will include this amount).
If you sum up both of your total incomes, yes, the amount will be more than you actually received in total, but your net incomes as a total will reflect the exact amount you received.
I hope this answers your question.
