Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22256, here are decompositions:

67 + 22189 = 22256
97 + 22159 = 22256
103 + 22153 = 22256
109 + 22147 = 22256
127 + 22129 = 22256
163 + 22093 = 22256
193 + 22063 = 22256
229 + 22027 = 22256

Showing the first eight; more decompositions exist.
