Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104868, here are decompositions:

17 + 104851 = 104868
19 + 104849 = 104868
37 + 104831 = 104868
41 + 104827 = 104868
67 + 104801 = 104868
79 + 104789 = 104868
89 + 104779 = 104868
107 + 104761 = 104868

Showing the first eight; more decompositions exist.
