Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666772, here are decompositions:

5 + 8666767 = 8666772
61 + 8666711 = 8666772
89 + 8666683 = 8666772
181 + 8666591 = 8666772
229 + 8666543 = 8666772
239 + 8666533 = 8666772
271 + 8666501 = 8666772
281 + 8666491 = 8666772

Showing the first eight; more decompositions exist.
