Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678160, here are decompositions:

11 + 8678149 = 8678160
13 + 8678147 = 8678160
19 + 8678141 = 8678160
31 + 8678129 = 8678160
47 + 8678113 = 8678160
67 + 8678093 = 8678160
79 + 8678081 = 8678160
97 + 8678063 = 8678160

Showing the first eight; more decompositions exist.
