Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671924, here are decompositions:

5 + 8671919 = 8671924
17 + 8671907 = 8671924
113 + 8671811 = 8671924
227 + 8671697 = 8671924
293 + 8671631 = 8671924
461 + 8671463 = 8671924
467 + 8671457 = 8671924
557 + 8671367 = 8671924

Showing the first eight; more decompositions exist.
