Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104800, here are decompositions:

11 + 104789 = 104800
41 + 104759 = 104800
71 + 104729 = 104800
83 + 104717 = 104800
89 + 104711 = 104800
107 + 104693 = 104800
149 + 104651 = 104800
239 + 104561 = 104800

Showing the first eight; more decompositions exist.
