Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22258, here are decompositions:

11 + 22247 = 22258
29 + 22229 = 22258
101 + 22157 = 22258
149 + 22109 = 22258
167 + 22091 = 22258
179 + 22079 = 22258
191 + 22067 = 22258
227 + 22031 = 22258

Showing the first eight; more decompositions exist.
