Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22818, here are decompositions:

7 + 22811 = 22818
11 + 22807 = 22818
31 + 22787 = 22818
41 + 22777 = 22818
67 + 22751 = 22818
79 + 22739 = 22818
97 + 22721 = 22818
101 + 22717 = 22818

Showing the first eight; more decompositions exist.
