Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22128, here are decompositions:

5 + 22123 = 22128
17 + 22111 = 22128
19 + 22109 = 22128
37 + 22091 = 22128
61 + 22067 = 22128
89 + 22039 = 22128
97 + 22031 = 22128
101 + 22027 = 22128

Showing the first eight; more decompositions exist.
