Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26830, here are decompositions:

17 + 26813 = 26830
29 + 26801 = 26830
47 + 26783 = 26830
53 + 26777 = 26830
71 + 26759 = 26830
101 + 26729 = 26830
107 + 26723 = 26830
113 + 26717 = 26830

Showing the first eight; more decompositions exist.
