Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182210, here are decompositions:

31 + 182179 = 182210
43 + 182167 = 182210
79 + 182131 = 182210
103 + 182107 = 182210
109 + 182101 = 182210
151 + 182059 = 182210
163 + 182047 = 182210
181 + 182029 = 182210

Showing the first eight; more decompositions exist.
