Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671760, here are decompositions:

127 + 8671633 = 8671760
211 + 8671549 = 8671760
241 + 8671519 = 8671760
313 + 8671447 = 8671760
367 + 8671393 = 8671760
379 + 8671381 = 8671760
397 + 8671363 = 8671760
421 + 8671339 = 8671760

Showing the first eight; more decompositions exist.
