I got a new #math term!
If u know about #twinPrimes, then also the rise of 67 ( #sixseven ) as a #meme, we should introduce 67 and 69 as "meme primes"!😂

Where prime is referring to important and not irreducible 😂

1416172 = sum of a pair of twin primes; each prime squared; four ways; no prime repeated:

= 227^2 + 229^2 + 809^2 + 811^2
= 179^2 + 181^2 + 821^2 + 823^2
= 149^2 + 151^2 + 827^2 + 829^2
= 521^2 + 523^2 + 659^2 + 661^2
