Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22158, here are decompositions:

5 + 22153 = 22158
11 + 22147 = 22158
29 + 22129 = 22158
47 + 22111 = 22158
67 + 22091 = 22158
79 + 22079 = 22158
107 + 22051 = 22158
127 + 22031 = 22158

Showing the first eight; more decompositions exist.
