Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656766, here are decompositions:

7 + 8656759 = 8656766
37 + 8656729 = 8656766
163 + 8656603 = 8656766
193 + 8656573 = 8656766
229 + 8656537 = 8656766
367 + 8656399 = 8656766
373 + 8656393 = 8656766
397 + 8656369 = 8656766

Showing the first eight; more decompositions exist.
