Single Curio View: (Seek other curios for this number) The number of distinct representations of a number n as the sum of two primes is at most the number of primes in the interval [n/2, n-2], and 210 is the largest value of n for which this upper bound is attained. In other words, 210 is the largest positive integer n that can be written as the sum of two primes in  (n - 2) - (n/2 - 1) distinct ways.
Reference: An
upper bound in Goldbach's problem. [Capelle]
