Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671956, here are decompositions:

19 + 8671937 = 8671956
37 + 8671919 = 8671956
317 + 8671639 = 8671956
367 + 8671589 = 8671956
373 + 8671583 = 8671956
383 + 8671573 = 8671956
439 + 8671517 = 8671956
457 + 8671499 = 8671956

Showing the first eight; more decompositions exist.
