Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671716, here are decompositions:

5 + 8671711 = 8671716
7 + 8671709 = 8671716
19 + 8671697 = 8671716
47 + 8671669 = 8671716
83 + 8671633 = 8671716
127 + 8671589 = 8671716
167 + 8671549 = 8671716
197 + 8671519 = 8671716

Showing the first eight; more decompositions exist.
