Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671128, here are decompositions:

29 + 8671099 = 8671128
31 + 8671097 = 8671128
61 + 8671067 = 8671128
71 + 8671057 = 8671128
97 + 8671031 = 8671128
131 + 8670997 = 8671128
139 + 8670989 = 8671128
181 + 8670947 = 8671128

Showing the first eight; more decompositions exist.
