Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740828, here are decompositions:

29 + 8740799 = 8740828
71 + 8740757 = 8740828
101 + 8740727 = 8740828
149 + 8740679 = 8740828
179 + 8740649 = 8740828
251 + 8740577 = 8740828
269 + 8740559 = 8740828
311 + 8740517 = 8740828

Showing the first eight; more decompositions exist.
