Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671566, here are decompositions:

17 + 8671549 = 8671566
47 + 8671519 = 8671566
67 + 8671499 = 8671566
97 + 8671469 = 8671566
103 + 8671463 = 8671566
109 + 8671457 = 8671566
139 + 8671427 = 8671566
157 + 8671409 = 8671566

Showing the first eight; more decompositions exist.
