Here are two important hints for our proof:
1. The gap between two consecutive primes can be arbitrarily long.
2. The probability there is a negative answer for Landau's Fourth Problem when [tex]n \ge i[/tex] is
[tex]\prod_{n=i}^{\infty}\frac{\pi(\sqrt{(2n)^2+1})}{(\pi(\sqrt{(2n)^2+1})+1)}= 0.[/tex]

We also observe that
[tex]k_{n }p_{n}[/tex] = [tex](2n)^{2}[/tex] + 1
where prime, [tex]p_{n}[/tex] is:
[tex]3 \le p_{n}\le\sqrt{k_{n}p_{n}} =\sqrt{(2n)^2+1}\le k_{n }.[/tex]
Note: [tex]k_{n }[/tex] = 1 is a violation when [tex]n \ge i.[/tex]
