Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740660, here are decompositions:

3 + 8740657 = 8740660
11 + 8740649 = 8740660
17 + 8740643 = 8740660
53 + 8740607 = 8740660
83 + 8740577 = 8740660
101 + 8740559 = 8740660
167 + 8740493 = 8740660
233 + 8740427 = 8740660

Showing the first eight; more decompositions exist.
