Rough Word-by-word:
he was Andrew the brother of Simon Peter one from/out of the two the ones who heard from John and had been following him

Smooth Translation:
Andrew, the brother of Simon Peter, was one of the two who heard from John and had been following him.

Or:
One of the two who heard from John and had been following him, was Andrew, the brother of Simon Peter.

Notes: I really had to look at the nominatives. It seems either one could be the predicate nominative and either one the subject.

The participial clauses are also interesting. "who heard from John" is attributive, but "had been following him" is predicate and has a pluperfect translation because of the imperfect verb.

This causes me to wonder if it is speaking about the fact that they had been followers of John rather than just those that had been following Jesus at the time He turned and spoke to them.
