OEIS Sequences

Primes equal to a sum of primes with differences congruent to (2,4) mod 6. A104160
Numbers m such that m-2, m-1, m+1, m+2 cannot all be represented in the form x·y + x + y for values x, y with x >= y > 1. A256386
For a lesser p of twin primes, let Bp+2 and Bp be sequences defined as A159559, but with initial terms p+2 and p respectively. The sequence lists p for which all differences Bp+2(n)-Bp(n)<=6. A276848
Prime numbers of the form 3p+8 where p, p+2 and p+6 are prime numbers. A376013
Primes p such that the differences between the 5 consecutive primes starting with p are (2,6,4,2). A78948
The sequence gives prime numbers formed from the sum of the squares of composite numbers and the corresponding prime numbers. A180233
Primes that can be generated by the concatenation in base 9, in descending order, of two consecutive integers read in base 10. A287313
a(n) = n - 2·floor(n/4). A83219
