Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26638, here are decompositions:

5 + 26633 = 26638
11 + 26627 = 26638
41 + 26597 = 26638
47 + 26591 = 26638
137 + 26501 = 26638
149 + 26489 = 26638
179 + 26459 = 26638
239 + 26399 = 26638

Showing the first eight; more decompositions exist.
