Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109666, here are decompositions:

3 + 109663 = 109666
5 + 109661 = 109666
47 + 109619 = 109666
83 + 109583 = 109666
149 + 109517 = 109666
197 + 109469 = 109666
233 + 109433 = 109666
269 + 109397 = 109666

Showing the first eight; more decompositions exist.
