Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671458, here are decompositions:

11 + 8671447 = 8671458
17 + 8671441 = 8671458
31 + 8671427 = 8671458
97 + 8671361 = 8671458
127 + 8671331 = 8671458
137 + 8671321 = 8671458
151 + 8671307 = 8671458
167 + 8671291 = 8671458

Showing the first eight; more decompositions exist.
