Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104778, here are decompositions:

5 + 104773 = 104778
17 + 104761 = 104778
19 + 104759 = 104778
61 + 104717 = 104778
67 + 104711 = 104778
71 + 104707 = 104778
97 + 104681 = 104778
101 + 104677 = 104778

Showing the first eight; more decompositions exist.
