Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740938, here are decompositions:

47 + 8740891 = 8740938
67 + 8740871 = 8740938
71 + 8740867 = 8740938
79 + 8740859 = 8740938
97 + 8740841 = 8740938
131 + 8740807 = 8740938
139 + 8740799 = 8740938
149 + 8740789 = 8740938

Showing the first eight; more decompositions exist.
