Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104680, here are decompositions:

3 + 104677 = 104680
29 + 104651 = 104680
41 + 104639 = 104680
83 + 104597 = 104680
101 + 104579 = 104680
131 + 104549 = 104680
137 + 104543 = 104680
167 + 104513 = 104680

Showing the first eight; more decompositions exist.
