Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104866, here are decompositions:

17 + 104849 = 104866
107 + 104759 = 104866
137 + 104729 = 104866
149 + 104717 = 104866
173 + 104693 = 104866
227 + 104639 = 104866
269 + 104597 = 104866
317 + 104549 = 104866

Showing the first eight; more decompositions exist.
