Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26438, here are decompositions:

7 + 26431 = 26438
31 + 26407 = 26438
67 + 26371 = 26438
211 + 26227 = 26438
229 + 26209 = 26438
277 + 26161 = 26438
331 + 26107 = 26438
397 + 26041 = 26438

Showing the first eight; more decompositions exist.
