An encrypted amount is an elgamal encryption in chunks. See concordium-base/types.rs at main · Concordium/concordium-base · GitHub

Decryption is normal elgamal decryption, plus brute forcing the exponent, see concordium-base/lib.rs at main · Concordium/concordium-base · GitHub for an implementation.

I hope this answers your question.
