Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20794, here are decompositions:

5 + 20789 = 20794
23 + 20771 = 20794
41 + 20753 = 20794
47 + 20747 = 20794
101 + 20693 = 20794
113 + 20681 = 20794
131 + 20663 = 20794
167 + 20627 = 20794

Showing the first eight; more decompositions exist.
