Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671964, here are decompositions:

127 + 8671837 = 8671964
331 + 8671633 = 8671964
463 + 8671501 = 8671964
523 + 8671441 = 8671964
571 + 8671393 = 8671964
601 + 8671363 = 8671964
643 + 8671321 = 8671964
673 + 8671291 = 8671964

Showing the first eight; more decompositions exist.
