Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182146, here are decompositions:

5 + 182141 = 182146
17 + 182129 = 182146
23 + 182123 = 182146
47 + 182099 = 182146
89 + 182057 = 182146
137 + 182009 = 182146
149 + 181997 = 182146
179 + 181967 = 182146

Showing the first eight; more decompositions exist.
