Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9168, here are decompositions:

7 + 9161 = 9168
11 + 9157 = 9168
17 + 9151 = 9168
31 + 9137 = 9168
41 + 9127 = 9168
59 + 9109 = 9168
101 + 9067 = 9168
109 + 9059 = 9168

Showing the first eight; more decompositions exist.
