Since prime numbers are like irreducable blocks in the number system, can I say that:

"Any number, including prime themselves, is composed of the addition of primes?"

I have quickly checked for a few numbers up to 10 and could tell that it is True. I have also attached a picture to help with the explanation.

    Every even number is the sum of some 2s, and every odd number (above 1) is the sum of a 3 and some 2s. – Greg Martin Sep 30 '20 at 01:41

    @bof , yes, that was my thought too, but since OP is very likely not a native speaker of English (and probably not of any other Indo-European language either), I think we should cut them some slack. (It did jar the sensibility.) – Lubin Sep 30 '20 at 04:00

    @YiXiangChong FYI, from Complete sequence, a related concept is that $1$, along with the set of primes, forms a "complete sequence", i.e., a set where "... every positive integer can be expressed as a sum of values in the sequence, using each value at most once". – John Omielan Sep 30 '20 at 04:24
  • @bof and Lubin. Thank you I have edited and improved the grammar from 'are' to 'is' – Yi Xiang Chong Sep 30 '20 at 05:23
