Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671312, here are decompositions:

5 + 8671307 = 8671312
179 + 8671133 = 8671312
281 + 8671031 = 8671312
443 + 8670869 = 8671312
449 + 8670863 = 8671312
521 + 8670791 = 8671312
569 + 8670743 = 8671312
599 + 8670713 = 8671312

Showing the first eight; more decompositions exist.
