Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671536, here are decompositions:

17 + 8671519 = 8671536
19 + 8671517 = 8671536
37 + 8671499 = 8671536
67 + 8671469 = 8671536
73 + 8671463 = 8671536
79 + 8671457 = 8671536
89 + 8671447 = 8671536
109 + 8671427 = 8671536

Showing the first eight; more decompositions exist.
