Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26566, here are decompositions:

5 + 26561 = 26566
53 + 26513 = 26566
107 + 26459 = 26566
149 + 26417 = 26566
167 + 26399 = 26566
173 + 26393 = 26566
179 + 26387 = 26566
227 + 26339 = 26566

Showing the first eight; more decompositions exist.
