Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26842, here are decompositions:

3 + 26839 = 26842
29 + 26813 = 26842
41 + 26801 = 26842
59 + 26783 = 26842
83 + 26759 = 26842
113 + 26729 = 26842
131 + 26711 = 26842
149 + 26693 = 26842

Showing the first eight; more decompositions exist.
