Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22720, here are decompositions:

3 + 22717 = 22720
11 + 22709 = 22720
23 + 22697 = 22720
29 + 22691 = 22720
41 + 22679 = 22720
83 + 22637 = 22720
101 + 22619 = 22720
107 + 22613 = 22720

Showing the first eight; more decompositions exist.
