Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22730, here are decompositions:

3 + 22727 = 22730
13 + 22717 = 22730
31 + 22699 = 22730
61 + 22669 = 22730
79 + 22651 = 22730
109 + 22621 = 22730
157 + 22573 = 22730
163 + 22567 = 22730

Showing the first eight; more decompositions exist.
