Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26890, here are decompositions:

11 + 26879 = 26890
29 + 26861 = 26890
41 + 26849 = 26890
89 + 26801 = 26890
107 + 26783 = 26890
113 + 26777 = 26890
131 + 26759 = 26890
167 + 26723 = 26890

Showing the first eight; more decompositions exist.
