LXX Gen 11:13

καὶ ἔζησεν Ἀρφαξάδ μετὰ τὸ γεννῆσαι αὐτὸν τὸν καινὰν ἔτη τετρακόσια τριάκοντα, καὶ ἐγέννησεν υἱοὺς καὶ θυγατέρας, καὶ ἀπέθανεν. Καὶ ἔζησεν καινὰν ἕκατον τριόκοντα ἴτη, κοὶ ἐγέννησεν τὸν Σόλο. καὶ ἔζησεν καινὰν μετὰ τὸ γεννῆσαι αὐτὸν τὸν Σάλα ἔτη τριοκόσια τριάκοντα, καὶ ἐγέννησεν υἱοὺς κοὶ θυγατέρας, καὶ ἀπέθανεν.

And after he had become the father of Shelah, Arphaxad lived 403 years and had other sons and daughters.
