[Woods] Every number greater than 55 is the sum of distinct primes of the form 4n + 3. [Wells] If sigma(n)/n is greater than 9, then n has at least 55 distinct prime factors. [Laatsch] Klimov (1975) showed that all integers are the sum of at most 55 prime numbers. 2^5555 is the largest nontitanic prime of form 2^nn, where n is a composite number. [Loungrides]
