Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671256, here are decompositions:

7 + 8671249 = 8671256
37 + 8671219 = 8671256
79 + 8671177 = 8671256
109 + 8671147 = 8671256
157 + 8671099 = 8671256
193 + 8671063 = 8671256
199 + 8671057 = 8671256
313 + 8670943 = 8671256

Showing the first eight; more decompositions exist.
