Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671278, here are decompositions:

29 + 8671249 = 8671278
47 + 8671231 = 8671278
59 + 8671219 = 8671278
101 + 8671177 = 8671278
127 + 8671151 = 8671278
131 + 8671147 = 8671278
151 + 8671127 = 8671278
179 + 8671099 = 8671278

Showing the first eight; more decompositions exist.
