Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168768, here are decompositions:

7 + 168761 = 168768
31 + 168737 = 168768
37 + 168731 = 168768
71 + 168697 = 168768
137 + 168631 = 168768
139 + 168629 = 168768
151 + 168617 = 168768
167 + 168601 = 168768

Showing the first eight; more decompositions exist.
