Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182156, here are decompositions:

67 + 182089 = 182156
97 + 182059 = 182156
109 + 182047 = 182156
127 + 182029 = 182156
199 + 181957 = 182156
229 + 181927 = 182156
283 + 181873 = 182156
367 + 181789 = 182156

Showing the first eight; more decompositions exist.
