Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26828, here are decompositions:

7 + 26821 = 26828
97 + 26731 = 26828
127 + 26701 = 26828
181 + 26647 = 26828
271 + 26557 = 26828
331 + 26497 = 26828
349 + 26479 = 26828
379 + 26449 = 26828

Showing the first eight; more decompositions exist.
