Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186700, here are decompositions:

11 + 186689 = 186700
29 + 186671 = 186700
47 + 186653 = 186700
53 + 186647 = 186700
71 + 186629 = 186700
113 + 186587 = 186700
131 + 186569 = 186700
149 + 186551 = 186700

Showing the first eight; more decompositions exist.
