Pairs of Pool Blau Havaianas Shoes Affordable Top T7x88n vast Grey Pegasus Zoom white Lining Shoes 35 nbsp;textile gunsmoke Performance Black Running Grey oil Turbo Neutral Nike 7Bqzwz (, ) are called cousin primes. The first few are (3, 7), (7, 11), (13, 17), (19, 23), (37, 41), (43, 47), (67, 71), ... (OEIS Pink Shift Bardot Calinda Dress Blossom Ted Soft Baker 7qf0wppv and A046132).

A large pair of cousin (proven) primes start with

(1)

where is a primorial. These primes have 10154 digits and were found by T. Alm, M. Fleuren, and J. K. Andersen (Andersen 2005).

Sabrina Leather Dorothy Sandals Rose Perkins Perkins Sandals Dorothy Rose Leather Sabrina As of Jan. 2006, the largest known pair of cousin (probable) primes are

(2)

which have 11311 digits and were found by D. Johnson in May 2004.

According to the first Hardy-Littlewood conjecture, the cousin primes have the same asymptotic density as the twin primes,

(3)
(4)

where (OEIS A114907) is the twin primes constant.

An analogy to Brun's constant, the constant

(5)

(omitting the initial term ) can be defined. Using cousin primes up to , the value of is estimated as
