Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22806, here are decompositions:

19 + 22787 = 22806
23 + 22783 = 22806
29 + 22777 = 22806
37 + 22769 = 22806
67 + 22739 = 22806
79 + 22727 = 22806
89 + 22717 = 22806
97 + 22709 = 22806

Showing the first eight; more decompositions exist.
