Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740666, here are decompositions:

17 + 8740649 = 8740666
23 + 8740643 = 8740666
59 + 8740607 = 8740666
89 + 8740577 = 8740666
107 + 8740559 = 8740666
149 + 8740517 = 8740666
173 + 8740493 = 8740666
239 + 8740427 = 8740666

Showing the first eight; more decompositions exist.
