We prove that the density of integers -2 (mod 24), which can be represented as the sum of two squares of primes and k powers of 4, tends to 1 as k Q . in the sequence k -0 (mod 3). Consequently, there exists a positive integer k 0 such that every large integer -4 (mod 24) is the sum of four squares
