Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660720, here are decompositions:

31 + 8660689 = 8660720
37 + 8660683 = 8660720
67 + 8660653 = 8660720
97 + 8660623 = 8660720
109 + 8660611 = 8660720
151 + 8660569 = 8660720
181 + 8660539 = 8660720
193 + 8660527 = 8660720

Showing the first eight; more decompositions exist.
