Список наи
меньших простых делителей каждого нечётного числа в интервале 316367053071733..624714112505847+8034, по 20 на строку, прочерк на правой границе означает что наименьший простой делитель больше
и его искать не стал ибо слишком долго, хотя число и вроде бы составное:

, т.е. каждое из них появилось лишь только справа или только слева от
, но не одновременно и там и там. Впрочем торможу, очевидно же, что и слева и справа может оказаться только число меньшее половины от
.
Разумеется я согласен что каждое простое объединяет не более двух интервалов, но Вы очевидно ошибаетесь с оценкой их размера.
) и тогда если в их общую границу попадёт следующее простое (в какой-то степени), то максимальный интервал почти удвоится за один шаг.
Конечно это очень маловероятно, но запрещено ли? Не уверен.
Мда, реально такого конечно не наблюдается, нашёл такие (для степени простого указан интервал слева от неё, справа и их сумма, лишь несколько примеров):
Интересно есть ли запрет и насколько сильный ...
Отдельно забавно что бывают и одинаковые интервалы слева и справа, но конечно не максимальные, например:
