Decomposition of Emirps
Emirps (primes whose reversal is a different prime).
Decomposition of Smith numbers
Smith (or joke) numbers: composite numbers n such that sum of digits of n = sum of digits of prime factors of n (counted with multiplicity).
Decomposition of A006881
Numbers that are the product of two distinct primes.
Decomposition of A006995
Numbers whose binary expansion is palindromic.
Decomposition of A007066
a(n) = 1 + ceiling((n-1)*phi^2), phi = (1+sqrt(5))/2.
Decomposition of A007304
Products of 3 distinct primes.
Decomposition of A007310
Numbers congruent to 1 or 5 mod 6.
Decomposition of A007378
a(n), n>=2, is smallest positive integer which is consistent with sequence being monotonically increasing and satisfying a(a(n)) = 2n.
Decomposition of A007412
The noncubes: n + [ (n + [ n^{1/3} ])^{1/3} ].
Decomposition of Reversible primes
Primes whose reversal in base 10 is also prime. Also called reversible primes.
