3*(10^31) + 2*(10^30) + 3*(10^29) + 9*(10^28) + ... + 8*10 + 7

Total of 32 parts.

You can add every two part if you want and you'll get something like:

32*(10^30) + 39*(10^28) + ... + 87

This will end up with only 16 parts, and so on. You can combine every two parts again so you'll have only 8 parts but the coefficients will become bigger and bigger, so you can decide which one is the best for you.

Good Luck !
