Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741240, here are decompositions:

7 + 8741233 = 8741240
37 + 8741203 = 8741240
97 + 8741143 = 8741240
103 + 8741137 = 8741240
199 + 8741041 = 8741240
241 + 8740999 = 8741240
349 + 8740891 = 8741240
373 + 8740867 = 8741240

Showing the first eight; more decompositions exist.
