Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671494, here are decompositions:

23 + 8671471 = 8671494
31 + 8671463 = 8671494
37 + 8671457 = 8671494
47 + 8671447 = 8671494
53 + 8671441 = 8671494
67 + 8671427 = 8671494
101 + 8671393 = 8671494
113 + 8671381 = 8671494

Showing the first eight; more decompositions exist.
