Prime and Ratio Pairs

Normal Sudoku rules apply. EVERY consecutive pair of numbers on all lines, moving away from the origin (where the three lines meet), is a prime number. Prime numbers overlap (ie: digit #2 for one prime becomes digit #1 for the next prime). Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are given. Thanks to Flycatcher, for the prime pairs line idea.
