Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26858, here are decompositions:

19 + 26839 = 26858
37 + 26821 = 26858
127 + 26731 = 26858
157 + 26701 = 26858
211 + 26647 = 26858
379 + 26479 = 26858
409 + 26449 = 26858
421 + 26437 = 26858

Showing the first eight; more decompositions exist.
