And secondly, per Tomas Oliveira e Silva, the number of twin primes have been calculated to at least 4*10^18 (about exp(42.833)). You want a twin prime count near exp(88), which is about 1.65*10^38. Yeah, I don’t foresee a calculation of that being feasible anytime soon.
30k{11,13;17,19;29,31}
so: every 30 integer only 6 prime test.
or
210k{...}
(7-2)*(5-2)*(3-2)=15 probably twin
so: 2*15/210
every 210 integer only 30 prime test:1/7,
30/210 * (2*88^8)=1,02752721373008e+15 primalize test

exp(88)=~1,65e+38

39 digit primalize test only 3 milisecond (poor technic 2019), so: every second 333 primalize test.
if we have 10e6 parellel processor then:

each proc. only 2*88^8/10e6=719269049 integer so only 719269049/7 =102752721 primalize test.
1,02752721373008e+15 /10e6/ 333/ 3600=85,7 hours

if we have 1e6 parellel processor then:
857 hours or 35 days

if you can have optimal technic (so:not use poor technic) only a few femto seconds need.

math must more groving for primalize test.
