Given 5 twos, 4 threes, 6 fives and 3 sevens create a multiplication problem , partial products included.
I believe the solution is unique.

It is true, that I've erred. I cannot say that I regret it , since my misgiving introduced 2 beautiful solutions of another version of my original puzzle.
I ERRED ELSEWHERE: just cfhange the title to "24 digits"and look for a unique (I believe- ??) solution. As you've noticed - and I did not- 3 digit multicand and 3 digit multiplier, with three 4 digit "partial products" and a 6 digits result gives 24 digits.
Sorry about imposing this extra task on you - and it is D4- BUT LET US CONSIDER IT A TEAM WORK - jointly creating a 3 level puzzle of 24 prime digits.
