Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671528, here are decompositions:

11 + 8671517 = 8671528
17 + 8671511 = 8671528
29 + 8671499 = 8671528
59 + 8671469 = 8671528
71 + 8671457 = 8671528
101 + 8671427 = 8671528
167 + 8671361 = 8671528
197 + 8671331 = 8671528

Showing the first eight; more decompositions exist.
