Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648160, here are decompositions:

11 + 8648149 = 8648160
29 + 8648131 = 8648160
47 + 8648113 = 8648160
61 + 8648099 = 8648160
67 + 8648093 = 8648160
127 + 8648033 = 8648160
163 + 8647997 = 8648160
167 + 8647993 = 8648160

Showing the first eight; more decompositions exist.
