Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168738, here are decompositions:

7 + 168731 = 168738
19 + 168719 = 168738
41 + 168697 = 168738
61 + 168677 = 168738
107 + 168631 = 168738
109 + 168629 = 168738
137 + 168601 = 168738
139 + 168599 = 168738

Showing the first eight; more decompositions exist.
