Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22740, here are decompositions:

13 + 22727 = 22740
19 + 22721 = 22740
23 + 22717 = 22740
31 + 22709 = 22740
41 + 22699 = 22740
43 + 22697 = 22740
61 + 22679 = 22740
71 + 22669 = 22740

Showing the first eight; more decompositions exist.
