Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104686, here are decompositions:

3 + 104683 = 104686
5 + 104681 = 104686
47 + 104639 = 104686
89 + 104597 = 104686
107 + 104579 = 104686
137 + 104549 = 104686
149 + 104537 = 104686
173 + 104513 = 104686

Showing the first eight; more decompositions exist.
