Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26688, here are decompositions:

5 + 26683 = 26688
7 + 26681 = 26688
19 + 26669 = 26688
41 + 26647 = 26688
47 + 26641 = 26688
61 + 26627 = 26688
97 + 26591 = 26688
127 + 26561 = 26688

Showing the first eight; more decompositions exist.
