You quoted commencement of Solomons temple from Wikipedia at 967 BC. Taking my Exodus date of 2553 and add 480 years is 967BC or 3033 from creation. I have them 315 years in Egypt. Also between the Septuagint which say 430 in Cannan and Egypt and the Masorectic text which says 430 years in Egypt.
I dont think the 4 generations who entered Egypt were living long enough to be in Egypt for 430 years. Since two generations entered I went scrubbing the first generation and saying the second generation were all newborns for maximum error. The fourth generation I substracted 40 years for being in the wilderness.
I have Jacob standing before Pharoah in year 2238 and adding 315 years gives me an Exodus date of 2553.
One more item to consider is Galations 3:15-18 in which a covenant can be a man's will.
15 To give a human example, brethren: no one annuls even a man’s will, or adds to it, once it has been ratified. 16 Now the promises were made to Abraham and to his offspring. It does not say, “And to offsprings,” referring to many; but, referring to one, “And to your offspring,” which is Christ. 17 This is what I mean: the law, which came four hundred and thirty years afterward, does not annul a covenant previously ratified by God, so as to make the promise void. 18 For if the inheritance is by the law, it is no longer by promise; but God gave it to Abraham by a promise.
I am not condemnng your work but sharing our differences.
I have 315 years in Egypt and 115 years in Cannan
