Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104878, here are decompositions:

29 + 104849 = 104878
47 + 104831 = 104878
89 + 104789 = 104878
149 + 104729 = 104878
167 + 104711 = 104878
197 + 104681 = 104878
227 + 104651 = 104878
239 + 104639 = 104878

Showing the first eight; more decompositions exist.
