Hi flora,
Thank you for your query,
The 35 plus years’ worth of NI payments you have will just be for your own State pension. To get a forecast of what state pension your wife is due to get when she reaches State Pension Age, she will have to request a State pension forecast from the Department for Work and pensions, please find the contact details below:

Unfortunately you can’t transfer National Insurance payments between spouses however there is a situation where you can transfer Child Benefit Credits. Please find the links below for a CF411 and CF411A forms if this interests you.
Apply for Home Responsibilities Protection - GOV.UK (www.gov.uk) (periods 1978-2010)
Apply for National Insurance credits if you’re a parent or carer - GOV.UK (www.gov.uk) (Periods 2010 Onwards).
Thank you.
