Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162306, here are decompositions:

13 + 162293 = 162306
17 + 162289 = 162306
19 + 162287 = 162306
29 + 162277 = 162306
37 + 162269 = 162306
43 + 162263 = 162306
97 + 162209 = 162306
163 + 162143 = 162306

Showing the first eight; more decompositions exist.
