Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182228, here are decompositions:

19 + 182209 = 182228
61 + 182167 = 182228
97 + 182131 = 182228
127 + 182101 = 182228
139 + 182089 = 182228
181 + 182047 = 182228
199 + 182029 = 182228
271 + 181957 = 182228

Showing the first eight; more decompositions exist.
