Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720736, here are decompositions:

7 + 8720729 = 8720736
23 + 8720713 = 8720736
29 + 8720707 = 8720736
43 + 8720693 = 8720736
47 + 8720689 = 8720736
107 + 8720629 = 8720736
109 + 8720627 = 8720736
113 + 8720623 = 8720736

Showing the first eight; more decompositions exist.
