Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740942, here are decompositions:

3 + 8740939 = 8740942
71 + 8740871 = 8740942
83 + 8740859 = 8740942
101 + 8740841 = 8740942
149 + 8740793 = 8740942
179 + 8740763 = 8740942
263 + 8740679 = 8740942
293 + 8740649 = 8740942

Showing the first eight; more decompositions exist.
