In general, the digits inside of each number should be descending from left to right, since the leftmost digits have a multiplier of 100.
So 8 and 9 occupy the leftmost digits, and 4 and 6 the second.
Pair 4 with the greater digit, i.e. 9, and 6 with the smaller (8).
Proceed this way for the rightmost digits.
Post what you've got if you wish.
