Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671158, here are decompositions:

7 + 8671151 = 8671158
11 + 8671147 = 8671158
31 + 8671127 = 8671158
59 + 8671099 = 8671158
61 + 8671097 = 8671158
101 + 8671057 = 8671158
107 + 8671051 = 8671158
127 + 8671031 = 8671158

Showing the first eight; more decompositions exist.
