Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20926, here are decompositions:

5 + 20921 = 20926
23 + 20903 = 20926
29 + 20897 = 20926
47 + 20879 = 20926
53 + 20873 = 20926
137 + 20789 = 20926
167 + 20759 = 20926
173 + 20753 = 20926

Showing the first eight; more decompositions exist.
