Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671510, here are decompositions:

11 + 8671499 = 8671510
41 + 8671469 = 8671510
47 + 8671463 = 8671510
53 + 8671457 = 8671510
83 + 8671427 = 8671510
101 + 8671409 = 8671510
149 + 8671361 = 8671510
179 + 8671331 = 8671510

Showing the first eight; more decompositions exist.
