Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671470, here are decompositions:

7 + 8671463 = 8671470
13 + 8671457 = 8671470
23 + 8671447 = 8671470
29 + 8671441 = 8671470
43 + 8671427 = 8671470
61 + 8671409 = 8671470
89 + 8671381 = 8671470
103 + 8671367 = 8671470

Showing the first eight; more decompositions exist.
