Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168156, here are decompositions:

5 + 168151 = 168156
13 + 168143 = 168156
29 + 168127 = 168156
47 + 168109 = 168156
67 + 168089 = 168156
73 + 168083 = 168156
89 + 168067 = 168156
113 + 168043 = 168156

Showing the first eight; more decompositions exist.
