Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671648, here are decompositions:

17 + 8671631 = 8671648
59 + 8671589 = 8671648
131 + 8671517 = 8671648
137 + 8671511 = 8671648
149 + 8671499 = 8671648
179 + 8671469 = 8671648
191 + 8671457 = 8671648
239 + 8671409 = 8671648

Showing the first eight; more decompositions exist.
