I just tried to understand the rules. Some points are not clear to me:
Is it allowed that two primes share a digit? E.g. the 3 in R4C4 is contained in instances of 13, 23, 31 and 37.
And if two pcn share a digit, do they touch orthogonally?
Do the rules apply to each instance of a prime?
The pcn 53 in R4C2/R5C1 touches the pcn 2 in R4C1.
