Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741180, here are decompositions:

31 + 8741149 = 8741180
37 + 8741143 = 8741180
43 + 8741137 = 8741180
61 + 8741119 = 8741180
109 + 8741071 = 8741180
127 + 8741053 = 8741180
139 + 8741041 = 8741180
181 + 8740999 = 8741180

Showing the first eight; more decompositions exist.
