Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671882, here are decompositions:

71 + 8671811 = 8671882
113 + 8671769 = 8671882
173 + 8671709 = 8671882
251 + 8671631 = 8671882
293 + 8671589 = 8671882
383 + 8671499 = 8671882
419 + 8671463 = 8671882
521 + 8671361 = 8671882

Showing the first eight; more decompositions exist.
