Slices of PI E - Part 1

Author Philippe_57721

We are reading the decimal parts of PI and E by slices of 10 digits:
PI = 1415926535, 8979323846, 2643383279, 5028841971,...
E = 7182818284, 5904523536, 0287471352, 6624977572,...

What is the "first" slice appearing in both constants?
"first" means it requires the minimum numbers of digits in the decimal parts.
For slices of 5 digits, the answer would be: 32823
