Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26278, here are decompositions:

11 + 26267 = 26278
17 + 26261 = 26278
29 + 26249 = 26278
41 + 26237 = 26278
89 + 26189 = 26278
101 + 26177 = 26278
107 + 26171 = 26278
137 + 26141 = 26278

Showing the first eight; more decompositions exist.
