Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182222, here are decompositions:

13 + 182209 = 182222
43 + 182179 = 182222
163 + 182059 = 182222
181 + 182041 = 182222
193 + 182029 = 182222
211 + 182011 = 182222
241 + 181981 = 182222
331 + 181891 = 182222

Showing the first eight; more decompositions exist.
