Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26728, here are decompositions:

5 + 26723 = 26728
11 + 26717 = 26728
17 + 26711 = 26728
29 + 26699 = 26728
41 + 26687 = 26728
47 + 26681 = 26728
59 + 26669 = 26728
101 + 26627 = 26728

Showing the first eight; more decompositions exist.
