Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656080, here are decompositions:

11 + 8656069 = 8656080
23 + 8656057 = 8656080
47 + 8656033 = 8656080
61 + 8656019 = 8656080
89 + 8655991 = 8656080
113 + 8655967 = 8656080
127 + 8655953 = 8656080
157 + 8655923 = 8656080

Showing the first eight; more decompositions exist.
