Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741264, here are decompositions:

13 + 8741251 = 8741264
31 + 8741233 = 8741264
61 + 8741203 = 8741264
73 + 8741191 = 8741264
127 + 8741137 = 8741264
193 + 8741071 = 8741264
211 + 8741053 = 8741264
223 + 8741041 = 8741264

Showing the first eight; more decompositions exist.
