Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168786, here are decompositions:

5 + 168781 = 168786
17 + 168769 = 168786
43 + 168743 = 168786
67 + 168719 = 168786
73 + 168713 = 168786
89 + 168697 = 168786
109 + 168677 = 168786
113 + 168673 = 168786

Showing the first eight; more decompositions exist.
