Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671266, here are decompositions:

17 + 8671249 = 8671266
47 + 8671219 = 8671266
73 + 8671193 = 8671266
89 + 8671177 = 8671266
139 + 8671127 = 8671266
167 + 8671099 = 8671266
199 + 8671067 = 8671266
257 + 8671009 = 8671266

Showing the first eight; more decompositions exist.
