Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740878, here are decompositions:

7 + 8740871 = 8740878
11 + 8740867 = 8740878
19 + 8740859 = 8740878
37 + 8740841 = 8740878
71 + 8740807 = 8740878
79 + 8740799 = 8740878
89 + 8740789 = 8740878
151 + 8740727 = 8740878

Showing the first eight; more decompositions exist.
