Intuition behind counterexample of Euler's sum of powers conjecture

Even simply generating all quadruples $(a, b, c, d)$ with $1 \le a \le b \le c \le d \le 133$ should work fine. There are only about 13 million such quadruples. For each, we need to add together the f …

$Ax^2 + By^3$ representing infinitely many primes

Are there any known results of the form there are infinitely many primes of the form $Ax^2 + By^3$ for integers $A$, $B$? Assuming there are currently no known results of this form, what is the …
