Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26680, here are decompositions:

11 + 26669 = 26680
47 + 26633 = 26680
53 + 26627 = 26680
83 + 26597 = 26680
89 + 26591 = 26680
107 + 26573 = 26680
167 + 26513 = 26680
179 + 26501 = 26680

Showing the first eight; more decompositions exist.
