Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741280, here are decompositions:

11 + 8741269 = 8741280
29 + 8741251 = 8741280
47 + 8741233 = 8741280
89 + 8741191 = 8741280
127 + 8741153 = 8741280
131 + 8741149 = 8741280
137 + 8741143 = 8741280
139 + 8741141 = 8741280

Showing the first eight; more decompositions exist.
