Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741142, here are decompositions:

5 + 8741137 = 8741142
13 + 8741129 = 8741142
19 + 8741123 = 8741142
23 + 8741119 = 8741142
43 + 8741099 = 8741142
71 + 8741071 = 8741142
89 + 8741053 = 8741142
101 + 8741041 = 8741142

Showing the first eight; more decompositions exist.
