Galatians 1:11
But I make known to you, brethren, that the gospel which was preached by me is not according to man. 12 For I neither received it from man, nor was I taught it, but it came through the revelation of Jesus Christ.
Nothing said by Paul supersedes, revises, changes or amends anything in the Synoptic Gospels. If it it does the interpretation of Paul is wrong. You could learn everything needed for Salvation from the Gospels alone, but by themselves, Paul's letters are hollow.
