Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671168, here are decompositions:

17 + 8671151 = 8671168
41 + 8671127 = 8671168
71 + 8671097 = 8671168
101 + 8671067 = 8671168
137 + 8671031 = 8671168
179 + 8670989 = 8671168
227 + 8670941 = 8671168
281 + 8670887 = 8671168

Showing the first eight; more decompositions exist.
