Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656772, here are decompositions:

13 + 8656759 = 8656772
43 + 8656729 = 8656772
199 + 8656573 = 8656772
211 + 8656561 = 8656772
349 + 8656423 = 8656772
373 + 8656399 = 8656772
379 + 8656393 = 8656772
409 + 8656363 = 8656772

Showing the first eight; more decompositions exist.
