Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671488, here are decompositions:

17 + 8671471 = 8671488
19 + 8671469 = 8671488
31 + 8671457 = 8671488
41 + 8671447 = 8671488
47 + 8671441 = 8671488
61 + 8671427 = 8671488
79 + 8671409 = 8671488
107 + 8671381 = 8671488

Showing the first eight; more decompositions exist.
