Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741140, here are decompositions:

3 + 8741137 = 8741140
11 + 8741129 = 8741140
17 + 8741123 = 8741140
41 + 8741099 = 8741140
269 + 8740871 = 8741140
281 + 8740859 = 8741140
347 + 8740793 = 8741140
383 + 8740757 = 8741140

Showing the first eight; more decompositions exist.
