Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641168, here are decompositions:

71 + 8641097 = 8641168
89 + 8641079 = 8641168
191 + 8640977 = 8641168
257 + 8640911 = 8641168
281 + 8640887 = 8641168
401 + 8640767 = 8641168
449 + 8640719 = 8641168
461 + 8640707 = 8641168

Showing the first eight; more decompositions exist.
