Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961168, here are decompositions:

11 + 961157 = 961168
17 + 961151 = 961168
29 + 961139 = 961168
59 + 961109 = 961168
71 + 961097 = 961168
101 + 961067 = 961168
179 + 960989 = 961168
191 + 960977 = 961168

Showing the first eight; more decompositions exist.
