Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20884, here are decompositions:

5 + 20879 = 20884
11 + 20873 = 20884
113 + 20771 = 20884
131 + 20753 = 20884
137 + 20747 = 20884
167 + 20717 = 20884
191 + 20693 = 20884
257 + 20627 = 20884

Showing the first eight; more decompositions exist.
