Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20944, here are decompositions:

5 + 20939 = 20944
23 + 20921 = 20944
41 + 20903 = 20944
47 + 20897 = 20944
71 + 20873 = 20944
137 + 20807 = 20944
173 + 20771 = 20944
191 + 20753 = 20944

Showing the first eight; more decompositions exist.
