Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186850, here are decompositions:

89 + 186761 = 186850
107 + 186743 = 186850
149 + 186701 = 186850
179 + 186671 = 186850
197 + 186653 = 186850
263 + 186587 = 186850
269 + 186581 = 186850
281 + 186569 = 186850

Showing the first eight; more decompositions exist.
