Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182198, here are decompositions:

19 + 182179 = 182198
31 + 182167 = 182198
67 + 182131 = 182198
97 + 182101 = 182198
109 + 182089 = 182198
139 + 182059 = 182198
151 + 182047 = 182198
157 + 182041 = 182198

Showing the first eight; more decompositions exist.
