Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740656, here are decompositions:

7 + 8740649 = 8740656
13 + 8740643 = 8740656
53 + 8740603 = 8740656
79 + 8740577 = 8740656
97 + 8740559 = 8740656
137 + 8740519 = 8740656
139 + 8740517 = 8740656
163 + 8740493 = 8740656

Showing the first eight; more decompositions exist.
