Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104808, here are decompositions:

5 + 104803 = 104808
7 + 104801 = 104808
19 + 104789 = 104808
29 + 104779 = 104808
47 + 104761 = 104808
79 + 104729 = 104808
97 + 104711 = 104808
101 + 104707 = 104808

Showing the first eight; more decompositions exist.
