Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168216, here are decompositions:

5 + 168211 = 168216
19 + 168197 = 168216
23 + 168193 = 168216
73 + 168143 = 168216
89 + 168127 = 168216
107 + 168109 = 168216
127 + 168089 = 168216
149 + 168067 = 168216

Showing the first eight; more decompositions exist.
