Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20932, here are decompositions:

3 + 20929 = 20932
11 + 20921 = 20932
29 + 20903 = 20932
53 + 20879 = 20932
59 + 20873 = 20932
83 + 20849 = 20932
173 + 20759 = 20932
179 + 20753 = 20932

Showing the first eight; more decompositions exist.
