Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660772, here are decompositions:

5 + 8660767 = 8660772
19 + 8660753 = 8660772
31 + 8660741 = 8660772
73 + 8660699 = 8660772
79 + 8660693 = 8660772
83 + 8660689 = 8660772
89 + 8660683 = 8660772
101 + 8660671 = 8660772

Showing the first eight; more decompositions exist.
