Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22138, here are decompositions:

5 + 22133 = 22138
29 + 22109 = 22138
47 + 22091 = 22138
59 + 22079 = 22138
71 + 22067 = 22138
101 + 22037 = 22138
107 + 22031 = 22138
227 + 21911 = 22138

Showing the first eight; more decompositions exist.
