Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109660, here are decompositions:

41 + 109619 = 109660
71 + 109589 = 109660
113 + 109547 = 109660
179 + 109481 = 109660
191 + 109469 = 109660
227 + 109433 = 109660
263 + 109397 = 109660
269 + 109391 = 109660

Showing the first eight; more decompositions exist.
