Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104818, here are decompositions:

17 + 104801 = 104818
29 + 104789 = 104818
59 + 104759 = 104818
89 + 104729 = 104818
101 + 104717 = 104818
107 + 104711 = 104818
137 + 104681 = 104818
167 + 104651 = 104818

Showing the first eight; more decompositions exist.
