Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26878, here are decompositions:

17 + 26861 = 26878
29 + 26849 = 26878
101 + 26777 = 26878
149 + 26729 = 26878
167 + 26711 = 26878
179 + 26699 = 26878
191 + 26687 = 26878
197 + 26681 = 26878

Showing the first eight; more decompositions exist.
