Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105700, here are decompositions:

17 + 105683 = 105700
47 + 105653 = 105700
137 + 105563 = 105700
167 + 105533 = 105700
173 + 105527 = 105700
191 + 105509 = 105700
197 + 105503 = 105700
233 + 105467 = 105700

Showing the first eight; more decompositions exist.
