Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26800, here are decompositions:

17 + 26783 = 26800
23 + 26777 = 26800
41 + 26759 = 26800
71 + 26729 = 26800
83 + 26717 = 26800
89 + 26711 = 26800
101 + 26699 = 26800
107 + 26693 = 26800

Showing the first eight; more decompositions exist.
