Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671248, here are decompositions:

17 + 8671231 = 8671248
29 + 8671219 = 8671248
71 + 8671177 = 8671248
97 + 8671151 = 8671248
101 + 8671147 = 8671248
149 + 8671099 = 8671248
151 + 8671097 = 8671248
181 + 8671067 = 8671248

Showing the first eight; more decompositions exist.
