Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104644, here are decompositions:

5 + 104639 = 104644
47 + 104597 = 104644
83 + 104561 = 104644
101 + 104543 = 104644
107 + 104537 = 104644
131 + 104513 = 104644
173 + 104471 = 104644
227 + 104417 = 104644

Showing the first eight; more decompositions exist.
