Let K be a positive integer, be any partition of the sequence of squares of primes and a280892f82" title="Click to view the MathML source">s(K) be the smallest positive integer such that every sufficiently large integer can be written as the sum of no more than a280892f82" title="Click to view the MathML source">s(K) elements, which belong to one of the sets Ai. In this paper, we prove that s(K)≪ϵK2+ϵ for sufficiently small positive number ϵ and all K≥1.
