Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671560, here are decompositions:

11 + 8671549 = 8671560
41 + 8671519 = 8671560
43 + 8671517 = 8671560
59 + 8671501 = 8671560
61 + 8671499 = 8671560
89 + 8671471 = 8671560
97 + 8671463 = 8671560
103 + 8671457 = 8671560

Showing the first eight; more decompositions exist.
