Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651080, here are decompositions:

17 + 8651063 = 8651080
29 + 8651051 = 8651080
41 + 8651039 = 8651080
71 + 8651009 = 8651080
83 + 8650997 = 8651080
101 + 8650979 = 8651080
281 + 8650799 = 8651080
353 + 8650727 = 8651080

Showing the first eight; more decompositions exist.
