Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671766, here are decompositions:

97 + 8671669 = 8671766
127 + 8671639 = 8671766
193 + 8671573 = 8671766
373 + 8671393 = 8671766
547 + 8671219 = 8671766
619 + 8671147 = 8671766
709 + 8671057 = 8671766
757 + 8671009 = 8671766

Showing the first eight; more decompositions exist.
