Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671516, here are decompositions:

5 + 8671511 = 8671516
17 + 8671499 = 8671516
47 + 8671469 = 8671516
53 + 8671463 = 8671516
59 + 8671457 = 8671516
89 + 8671427 = 8671516
107 + 8671409 = 8671516
149 + 8671367 = 8671516

Showing the first eight; more decompositions exist.
