Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671786, here are decompositions:

17 + 8671769 = 8671786
47 + 8671739 = 8671786
89 + 8671697 = 8671786
197 + 8671589 = 8671786
269 + 8671517 = 8671786
317 + 8671469 = 8671786
359 + 8671427 = 8671786
419 + 8671367 = 8671786

Showing the first eight; more decompositions exist.
