I wrote a code to produce twin primes, however it is pretty strenuous for my computer and I need some high numbers to check a conjecture. Is there a better way to get twin primes. Note: these twin primes are represented by 6m's where 6m+-1 are prime.
n = 1:120000; m61 = n*6-1; Twins = []; for i=1:numel(m61); z = isprime(m61(i)); y = isprime(m61(i)+2); if ...
